Wi-Fi Problems

How Much Does a Wi-Fi Site Survey Cost in the UK?

Discover what affects the cost of a professional Wi-Fi Site Survey in the UK, including building size, survey type, complexity and reporting.

If you’re a business owner experiencing unreliable wireless connectivity, or an IT Manager responsible for your office or commercial wireless networks then you may well find yourself requiring a Wi-Fi Site Survey at some point.

This commonly comes up when Facilities Managers are planning building changes or relocating offices, but it also applies to businesses upgrading their existing Wi-Fi infrastructure.

Wi-Fi Site Surveys are also vital for organisations installing wireless networking in new premises and companies experiencing persistent coverage or performance problems.

A professional Wi-Fi Site Survey can be an invaluable tool to IT service providers, delivering specialist wireless surveying expertise.

How Much Does a Wi-Fi Site Survey Cost?

When it comes to Wi-Fi Surveys, there’s not a ‘one cost fits all’ solution.

The cost of a professional Wi-Fi site survey in the UK depends on:

The size and complexity of your office building
The type of survey required
The level of investigation involved

A straightforward office coverage assessment requires a different approach from designing a wireless network for a large warehouse or investigating persistent connectivity problems across multiple floors.

A tailored quotation should reflect the work needed to achieve your unique objectives.

What Factors Affect the Cost of a Wi-Fi Site Survey?

Wi-Fi Site Survey pricing reflects the complexity and scope of the work rather than, for example, something as simple as the number of Access Points installed. There are a number of factors that must be considered when planning a Wi-Fi Site Survey that will impact the overall cost.

Building Size and Number of Floors

Cost will depend on the size of the office building and how many floors it covers. Larger buildings generally require more physical surveying. Multiple floors also increase the area that must be assessed.

Likewise, if there are separate buildings they may also require additional measurements and planning.

The number of measurement locations will also be affected by long corridors, individual offices and partitioned spaces.

Access restrictions to the premises may increase the time required to complete the survey.

Floor plans can be hugely helpful to Wi-Fi engineers when estimating the likely work involved in a Wi-Fi Site Survey before visiting the premises.

It’s helpful to bear in mind that a larger building doesn’t automatically mean a more complicated wireless environment. For example, a large, open-plan office may be simpler to survey than a smaller building containing thick walls, complicated layouts or specialist equipment.

Building Materials and Construction

The materials used in building construction can affect wireless propagation, ie. the way the waves travel from a transmitting antenna to a receiving antenna.

Examples of building materials that can affect Wi-Fi signal include:

Reinforced concrete walls and floors.
Metal partitions and shelving.
Brick and stone walls.
Glass partitions with metallic coatings.
Insulated panels and foil-backed insulation.
Lift shafts and structural steelwork.

Depending on the material, they can attenuate or reflect radio-frequency signals differently. The effect can also vary between frequency bands.

For example, a building may have acceptable 2.4 GHz coverage while experiencing weaker 5 GHz coverage through certain walls.

The engineer must account for these differences when assessing coverage or designing Access Point placement.

Existing Wi-Fi Infrastructure

Your current wireless installation also affects Wi-Fi Site Survey requirements.

Factors for a Wi-Fi engineer to consider include:

Number and location of existing access points.
Wireless equipment manufacturer and model.
Existing channel and transmit-power configurations.
Available management and monitoring information.
Age and capabilities of the equipment.
Existing cabling and switching infrastructure.
Whether the network can be accessed for configuration or testing.

An existing installation may provide useful information, but it can also introduce additional troubleshooting work.

For example, identifying whether poor performance originates from the wireless network, switching infrastructure or internet connection may require more investigation than a straightforward coverage survey.

Business Applications and Performance Requirements

Wireless networks should be designed around how they will be used.

What does your business need from the Wi-Fi? Our clients commonly need the following to be functional:

General office internet access.
Microsoft Teams and other real-time communication applications.
Voice over Wi-Fi.
Warehouse barcode scanners.
Mobile payment terminals.
Guest wireless access.
Industrial equipment.
High-density meeting rooms.

A network supporting basic web browsing will likely have different performance requirements from one supporting real-time voice communications or mobile scanners.

Wi-Fi Site Survey objectives may therefore include:

Signal strength
Signal-to-noise ratio
Channel utilisation
Roaming behaviour
Throughput
Application performance

Remember that not every survey measures every performance characteristic. Measurements should be selected according to the agreed scope.

Accessibility and Working Conditions

Survey logistics can influence the overall work required. There are several factors to consider when planning the practical side of completing a Wi-Fi Survey, and these bring legitimate pricing differences.

Logistical factors to consider when pricing up a Wi-Fi Site Survey include:

Out-of-hours access.
Occupied offices.
Restricted operational areas.
Warehouses requiring safety inductions.
Large outdoor areas.
Multiple buildings.
Secure or sensitive environments.
Sites where normal business operations cannot be interrupted.

How Do Different Types of Wi-Fi Site Surveys Affect the Cost?

Different Wi-Fi surveying techniques answer different network questions.

A professional wireless survey provider should recommend an appropriate methodology rather than automatically offering the same service to every customer.

Predictive Wi-Fi Site Surveys

A Predictive Wi-Fi Survey uses software to model wireless coverage before equipment is installed.

Predictive Wi-Fi Surveys rely on building floor plans and estimations of construction materials. They model how wireless signals may propagate through the estimated environment.

This model helps determine potential Access Point locations as well as supporting decisions about Access Point quantities and equipment selection.

A Predictive Wi-Fi Survey can also model different frequency bands and design assumptions.

This type of survey is particularly useful for:

New buildings
Refurbishments
Office relocations

The predictive nature of this survey may reduce the risk of installing Access Points in unsuitable locations.

Of course, the accuracy of predictive modelling depends on the accuracy of the information supplied to feed into the model.

It’s important to note that a predictive survey is not the same as physically measuring wireless performance in a completed building.

Where Wi-Fi performance is business-critical, subsequent validation may be appropriate.

Passive Wi-Fi Site Surveys

A Passive Survey measures wireless signals present within an environment without requiring the surveying device to associate with each measured network.

It can provide information about:

Received signal strength.
Available wireless networks.
Channel allocation.
Observed access point coverage.
Signal-to-noise ratio, where supported.
Overlapping wireless coverage.
Potential co-channel contention.

Passive surveying is useful for understanding the RF environment and identifying coverage or channel-planning concerns.

Passive surveying alone does not establish actual application performance or prove that a client can successfully communicate across the network.

Active Wi-Fi Site Surveys

An active Wi-Fi Site Survey involves connecting to the wireless network and performing measurements.

Depending on the methodology, these may include:

Network connectivity.
Throughput.
Latency.
Packet loss.
Roaming performance.
Connectivity to internal services.
Application-specific performance.

Active surveying can help determine whether wireless coverage translates into usable connectivity. Active measurements depend on the capabilities of the test client and the wider network.

Post-Installation Validation Surveys

A Validation Survey checks whether a completed installation meets its intended requirements.

It may identify:

Unexpected coverage gaps.
Poor access point positioning.
Incorrect channel configuration.
Excessive transmit power.
Roaming problems.
Areas where performance differs from the original design.

A Validation Survey may be particularly valuable after a substantial wireless installation.

How Long Does a Professional Wi-Fi Site Survey Take?

The time required to complete a Wi-Fi Site Survey depends on the size of the premises and the scope of the survey.

Small premises may require a relatively short on-site visit. Large or complicated buildings can require significantly more time.

Surveying multiple floors or separate buildings increases the work involved.

Detailed troubleshooting may require additional testing. Measuring application performance can take longer than collecting basic RF coverage information.

Some projects require testing under representative operating conditions. A building that is empty during the survey may behave differently when fully occupied.

The work continues after we’ve left

Wi-Fi Site Surveying is not just the time spent walking around the premises.

Post-survey work may include:

Reviewing collected measurements.
Analysing coverage and interference.
Producing wireless heatmaps.
Identifying configuration problems.
Reviewing Access Point placement.
Developing practical recommendations.
Preparing a written report.

You may see a Wi-Fi engineer on-site for a relatively short period, but significant time is spent doing the associated analysis involved afterwards.

What’s Included in the Cost of a Professional Wi-Fi Site Survey?

The deliverables on a Wi-Fi Site Survey depend on the agreed scope.

A professional survey should provide useful evidence and recommendations rather than just a collection of measurements.

Initial Consultation and Requirements

The initial consultation prior to a Wi-Fi Site Survey is there to provide understanding of your existing wireless network and any problems you are currently experiencing.

We also establish exactly how your Wi-Fi network is used and identify any business-critical applications.

At the end of this consultation we can agree on the objectives of the Wi-Fi Survey.

On-Site Wireless Assessment

Depending on the type of Wi-Fi Survey selected, an on-site Wireless Assessment may involve:

Measuring wireless signal strength.
Investigating coverage gaps.
Reviewing channel allocation.
Assessing the surrounding RF environment.
Checking Access Point locations.
Reviewing wireless configurations.
Performing connectivity or performance tests.
Identifying potential interference sources.

Analysis and Reporting

Once the measurements have been taken, they are then all analysed and compiled into a report, which may contain:

Wireless coverage heatmaps.
Technical observations.
Identification of confirmed problems.
Recommended improvements.
Suggested Access Point changes.
Channel and transmit-power recommendations.
Equipment upgrade considerations.

It can also recommend any further investigations if they are necessary.

Geekabit Expertise

The Wi-Fi engineers at Geekabit use specialist tools appropriate to each individual assignment, including:

Hamina Wireless for wireless planning, surveying and analysis.
WLAN Pi for network and wireless diagnostics.
Wi-Fi Explorer Pro for wireless environment analysis.
Professional network testing equipment where relevant.

Not every specialist tool is used in every survey, but guided by your individual requirements.

We have both the professional equipment to help our expert Wi-Fi engineers to collect and interpret evidence, as well as the engineer’s experience to interpret the results.

Is a Cheap Wi-Fi Site Survey Worth It?

There is a difference between price and value. What matters is that the Wi-Fi Survey being done is the right one, and that you can use the information gleaned from it to make sure your network is functioning at the optimum level.

Different surveys have different objectives.

A small business with a clearly defined problem can benefit from a simple coverage check. A large business or business-critical environment may need a more comprehensive survey.

A basic Wi-Fi analyser cannot provide the same information as a properly scoped professional survey.

It’s also worth remembering that collecting signal strength readings does not necessarily explain why users are experiencing poor performance.

A Wi-Fi Survey should investigate the relevant technical characteristics rather than just produce attractive heatmaps.

What are you buying?

As the client, you should always understand what you are purchasing.

Useful questions to ask your Wi-Fi Site Surveyor might include:

Will the survey include on-site measurements?
Will the engineer assess the existing wireless configuration?
Are performance tests included?
Will the report contain practical recommendations?
Are heatmaps included where relevant?
Does the quotation include analysis and reporting?
Will the survey investigate our specific problem?

The cheapest survey is not necessarily the best value, but the most comprehensive survey is not always necessary either.

Can a Professional Wi-Fi Site Survey Save Your Business Money?

Investing in a professional Wi-Fi Survey can help your business avoid unnecessary expenditure.

Avoiding Unnecessary Access Points

A common assumption is that poor Wi-Fi performance can be resolved by installing additional Access Points. This assumption is not always correct.

Potential problems with just deploying more Access Points to try and resolve a Wi-Fi issue include:

Co-channel contention.
Excessive overlapping coverage.
Poor channel allocation.
Inappropriate transmit-power settings.
Client devices connecting to unsuitable access points.
Interference from neighbouring wireless networks.

Adding more Access Points without understanding the existing environment may fail to resolve the problem and can sometimes make performance even worse!

Reducing Installation Mistakes

Predictive design and surveying can help reduce the likelihood of:

Installing Access Points in unsuitable locations.
Discovering coverage gaps after installation.
Having to relocate equipment.
Repeating cabling work.
Purchasing unnecessary hardware.

Identifying the Actual Cause of Poor Performance

Slow Wi-Fi is not always caused by inadequate signal strength.

Other causes of slow Wi-Fi may include:

Network congestion.
Interference.
Incorrect configuration.
Client device limitations.
Faulty cabling.
Switching problems.
Internet connection limitations.

A well-scoped investigation can help distinguish wireless problems from faults elsewhere in the network.

Whilst a Wi-Fi Survey could help save a business money by reducing the likelihood of buying unnecessary hardware, reducing installation mistakes and finding the cause of poor Wi-Fi, we can’t guarantee you that there will be tangible savings or that a survey will identify every possible fault.

Hopefully, however, we’ve demonstrated in this article the many benefits of employing a Wi-Fi professional to carry out a Wi-Fi Site Survey.

How to Get an Accurate Wi-Fi Site Survey Quote

Providing useful information at the enquiry stage allows a Wi-Fi specialist to recommend the right level of assessment.

Information we will ask you, as the client, to provide:

Location of the premises.
Approximate building size.
Number of floors.
Available floor plans.
Type of business environment.
Whether the Wi-Fi network already exists.
Number of existing access points, if known.
Main wireless connectivity problems.
Number and type of connected devices.
Business-critical applications.
Whether the project involves troubleshooting, expansion or a new installation.
Any site access restrictions.
Desired timescales.

Frequently Asked Questions

How much does a Wi-Fi site survey cost in the UK?

The cost of a professional Wi-Fi site survey depends on several factors, including building size, construction materials, the number of floors and the type of survey required. A predictive survey for a new office has different requirements from an active survey investigating performance problems across an existing wireless network. The level of reporting and analysis also influences the work involved. For an accurate quotation, a specialist should first establish the size of the premises, the intended use of the network and the objectives of the survey.

Is a professional Wi-Fi site survey worth the money?

A professional Wi-Fi site survey can be valuable when a business is experiencing persistent connectivity problems, planning a wireless network upgrade or installing Wi-Fi in new premises. Survey measurements help engineers identify coverage limitations, channel-planning problems and other factors affecting wireless performance. This can reduce the risk of unnecessary equipment purchases or unsuitable access point placement. However, not every Wi-Fi problem requires a comprehensive survey. A smaller assessment or targeted troubleshooting exercise may be more appropriate for straightforward issues.

How long does a Wi-Fi site survey take?

The time required depends on the size and complexity of the building and the type of measurements being collected. A relatively small office may require a shorter visit than a multi-storey building or warehouse. Surveys involving detailed performance testing, multiple wireless networks or complex environments can take longer. The on-site visit is only part of the process. Engineers may also need to analyse measurements, prepare coverage heatmaps and produce a report containing findings and recommendations.

Can I carry out a Wi-Fi site survey myself?

Basic Wi-Fi analysis applications can help identify nearby networks, signal strength and some channel interference. The feasibility depends heavily on the size of your space and how much accuracy you need.

Can You Have Too Many Wi-Fi Access Points?

Can too many Wi-Fi access points slow down your network? Discover how interference, poor placement and channel planning can affect your business Wi-Fi.

How Many Wi-Fi Access Points is Too Many?

The number of Access Points alone doesn’t determine whether a network is well designed.

It is possible to have too many Wi-Fi Access Points. Installing additional Access Points without proper planning can increase interference, create unnecessary competition for wireless airtime and potentially reduce your network performance.

Office Managers, Facilities Managers and even IT Managers can often assume that weak or unreliable Wi-Fi means they must need additional Access Points.

This assumption is completely understandable because:

More Access Points should theoretically provide more coverage.
Additional APs can help eliminate areas with weak signals.
Wi-Fi equipment is increasingly affordable and relatively straightforward to install.
Many business networking products advertise simple installation and automatic optimisation.

However, Wi-Fi is fundamentally different from a wired network.

When additional Ethernet ports are installed, each connected device generally receives its own dedicated switched connection.

Wireless devices, by comparison, must share a limited amount of radio spectrum.

Adding another Access Point doesn’t automatically create more usable wireless capacity, particularly when nearby Access Points are operating on the same channels.

Real-World Example of Why More AP’s Doesn’t Mean Better Wi-Fi

Let’s take you through a real-world example. Imagine you’re working in a small office and the staff are experiencing slow Wi-Fi.

The business has four Access Points and decides to install another four.

Although signal strength might improve in some locations, the additional APs could increase competition for the available wireless channels.

If the original problem was already caused by excessive channel utilisation, the additional equipment might actually make matters even worse.

Understanding why this happens requires looking at how Wi-Fi Access Points communicate and share radio spectrum.

What Happens When You Install Too Many Wi-Fi Access Points?

Installing too many Access Points without proper planning can cause various issues with your wireless network. When installing Access Points to your business Wi-Fi network, it’s important to consider a number of factors.

Co-Channel Interference: When Access Points Share the Same Channel

Wi-Fi Access Points operating on the same channel within radio range generally have to share the available airtime.

Wi-Fi uses mechanisms designed to reduce simultaneous transmissions on the same channel.

When an Access Point or wireless client detects that the channel is busy, it may need to wait before transmitting.

Multiple Access Points can operate on the same channel. In larger networks, this is normal. However, any Access Points and clients sharing a channel may compete for airtime. As the number of active devices increases, available transmission opportunities become more limited. This can increase latency and reduce throughput.

Co-channel interference is caused when more than one Access Point is contending for the same channel. Generally speaking, devices that can detect one another can coordinate access to the channel rather than just corrupting each other’s transmissions. But, excessive contention between Access Points can significantly affect your Wi-Fi performance.

Real World Example of Too Many AP’s Sharing the Same Channel

Imagine your office has three Access Points operating on the same 5 GHz channel.

If all three are within radio range and serving busy clients, they may effectively be sharing the available channel airtime.

Adding another Access Point to that same channel doesn’t automatically provide another channel’s worth of capacity.

It may simply introduce another set of devices competing for the existing airtime.

Adjacent-Channel Interference: When Channels Overlap

Adjacent-channel interference is different from co-channel contention.

It occurs when transmissions on overlapping or insufficiently separated channels interfere with one another.

This can be particularly problematic because devices may not coordinate their transmissions effectively.

Key points to consider with Adjacent-Channel Interference:

Wi-Fi channels occupy portions of the radio spectrum.
Some channel configurations overlap.
Wider channels consume more spectrum.
Poor channel planning can increase interference.
Interference can cause retransmissions and reduce usable throughput.

The problem with 2.4 GHz

The 2.4 GHz band provides relatively little usable spectrum.

In the UK, channels 1, 6 and 11 are a commonly used non-overlapping arrangement for 20 MHz Wi-Fi channels.

Installing numerous Access Points using inappropriate channel configurations can create unnecessary interference.

Using 40 MHz channels on 2.4 GHz is generally undesirable in typical business environments because it consumes much of the available spectrum.

5 GHz and 6 GHz Channels

These bands offer additional channel-planning opportunities, but they’re not unlimited resources.

In particular:

Channel width affects how many independent channels are available.
Wider channels can provide higher potential speeds but reduce channel reuse opportunities.
Dense installations may benefit from narrower channels.
Channel availability depends on regulatory requirements and equipment capabilities.

However, we’re certainly not suggesting that 6 GHz completely eliminates interference problems.

Excessive Coverage Overlap

When planning and installing a wireless network for business, some overlap between Access Points is essential.

Businesses need continuous coverage as employees move between offices, meeting rooms and communal areas.

However, excessive overlap can create problems.

The key points to consider with coverage overlap when installing AP’s in a business network are:

Multiple Access Points may provide strong signals in the same location.
Clients might detect many suitable APs simultaneously.
Poorly configured transmit power can make AP selection and roaming less predictable.
Excessive overlap can contribute to co-channel contention when the same channels are reused.
AP placement should balance coverage, capacity and roaming requirements.

Coverage overlap alone doesn’t automatically cause interference. The impact depends on channel assignments, signal levels, client behaviour and traffic.

A successful Wi-Fi design doesn’t aim to eliminate overlapping coverage. It aims to provide sufficient overlap for reliable connectivity while minimising unnecessary contention.

Five Signs Your Office Might Have Too Many Wi-Fi Access Points

Do you recognise any of these potential problems within your own workplace?

Whilst these issues could indicate a problem with too many Access Points, it’s important to remember that these symptoms aren’t definitive proof of excessive Access Points in your business network. There could also be other network issues at play.

If you’re not sure of the cause of your network problems, then it’s always advisable to seek the help of a Wi-Fi professional.

Sign 1: Your Wi-Fi Signal Is Excellent, but Performance Is Poor

Strong Wi-Fi signal strength doesn’t necessarily mean fast Wi-Fi.

A device might display full Wi-Fi signal bars while experiencing:

Slow downloads.
Delayed video calls.
Poor application responsiveness.
High latency.
Inconsistent throughput.

This can happen when the wireless channel is heavily utilised or affected by interference.

Signal strength measures only part of the wireless experience.

Sign 2: Wi-Fi Becomes Slower When the Office Gets Busy

Wireless airtime is shared.

When more employees arrive and begin using their devices, competition for airtime increases.

Think about your office environment – Your employees or colleagues likely use:

Laptops.
Smartphones.
Wireless headsets and collaboration devices.
Video conferencing systems.
Guest devices.

If numerous Access Points are competing for the same channels, the network may struggle during periods of high activity.

However, remember that increased demand can also indicate insufficient capacity rather than too many APs.

The solution depends on identifying the actual bottleneck. Don’t be afraid to seek the help of a professional Wi-Fi engineer to diagnose the problem.

Sign 3: Devices Don’t Always Connect to the Best Access Point

Wireless clients generally make their own decisions about which Access Point to connect to.

An employee might walk from one side of an office to another while their laptop remains connected to an AP farther away.

This is sometimes described as a sticky client.

Clients don’t always select the physically nearest Access Point. This can be due to excessive transmit power where clients remain connected to distant APs.

Roaming behaviour varies between devices. Proper AP positioning and power configuration can improve the roaming conditions in your office.

Features such as 802.11k, 802.11v and 802.11r may help where supported and appropriately configured.

Adding Access Points doesn’t automatically cause roaming failures, but can be a contributing factor when placement and power aren’t considered or managed appropriately.

Sign 4: Wi-Fi Performance Varies Between Rooms

Unfortunately, users can experience different performance even when signal strength appears similar.

Possible causes include:

Different levels of channel utilisation.
Interference from neighbouring Access Points.
Building materials.
Poor AP positioning.
Client distribution.
Channel width and power configuration.

One example of this could be the use of meeting rooms.

A meeting room containing ten people on video calls may need considerably more capacity than a similarly sized storage room.

The number of APs required depends on usage, not just floor area.

Sign 5: You’ve Installed More Access Points, but Nothing Has Improved

This one is probably the strongest commercial indicator of too many AP’s causing problems for your business Wi-Fi network.

Just adding equipment without investigating the problem can lead to unnecessary expenditure.

The original issue might be:

Poor channel planning.
Inappropriate AP placement.
Excessive channel utilisation.
Incorrect transmit power.
Insufficient capacity in specific areas.
A wired network or internet connection bottleneck.

Before purchasing another Access Point, businesses should understand what’s actually causing their wireless performance problems. If you’re not confident on how to do that, then invest in a Wi-Fi Survey from a wireless network professional.

Spending money on a Wi-Fi Survey could end up saving you money on unnecessary hardware and more network problems down the line.

Is It Better to Have Fewer, More Powerful Wi-Fi Access Points?

Another common misconception when it comes to business Wi-Fi networks is the assumption that fewer APs operating at maximum transmit power will deliver better results.

This isn’t necessarily true.

Wi-Fi Communication Works in Both Directions

An Access Point needs to communicate with the client, but the client also needs to communicate back.

An AP might transmit at a relatively high power level, while a smartphone or laptop has a lower transmission capability.

This can create an imbalance.

The client may detect a strong signal from the AP but struggle to communicate reliably in the opposite direction.

Increasing AP transmit power doesn’t automatically improve the quality of a wireless connection.

Why Lower Transmit Power Can Sometimes Help

Reducing transmit power can sometimes:

Reduce unnecessary coverage overlap.
Improve channel reuse.
Encourage clients to associate with more appropriate APs.
Reduce contention between distant cells using the same channel.

However, transmit power shouldn’t simply be reduced everywhere.

Excessive reductions can create coverage gaps or unreliable connections.

Why Fewer APs Aren’t Always Better

High-density environments may genuinely require more Access Points.

Examples of situations where more AP’s may be helpful in a business Wi-Fi network include:

Conference facilities.
Busy meeting rooms.
Training centres.
Large open-plan offices.
Warehouses using wireless handheld devices.

The correct approach is to design around coverage, capacity and application requirements.

The objective isn’t to install the fewest possible Access Points. It’s to install the appropriate number and configure them correctly.

How Do Wi-Fi Professionals Determine the Right Number of Access Points?

Professional Wi-Fi design involves more than counting rooms or calculating floor area.

There are three important elements when designing and deploying a business Wi-Fi network.

Predictive Wi-Fi Design

Here at Geekabit, our Wi-Fi engineers use specialist software to model wireless coverage before equipment is even installed.

Geekabit uses professional Wi-Fi planning tools, including Hamina, to help design wireless networks.

What’s the process of predictive Wi-Fi design? A predictive design may consider:

Building floor plans.
Wall locations and construction materials.
Ceiling heights.
Expected numbers of users.
Wireless applications.
Available frequency bands.
Access point models and antenna characteristics.
Proposed AP positions and transmit power.

The software can generate predictive coverage maps showing how signals are expected to propagate throughout your office building. This means that we can see how repositioning an AP could change the predicted coverage without necessarily increasing the number of APs.

Whilst specialist predictive software are brilliant tools in the world of Wi-Fi, remember that predictive designs are models.

Their accuracy depends on the quality of the information provided and the assumptions used.

Where appropriate, onsite validation is needed to confirm actual performance.

Imagery: Hamina predictive coverage heatmap.

Professional Wi-Fi Site Surveys

Wi-Fi Site Surveys allow wireless engineers to assess real-world conditions.

Depending on the project, this might involve:

Passive surveys

Measuring the wireless environment, including signal strength, channel usage and surrounding networks.

Active surveys

Connecting to the network to assess aspects of client connectivity and performance.

Spectrum analysis

Investigating radio-frequency activity, including sources that might not be standard Wi-Fi transmissions.

A site survey can help identify:

Coverage gaps.
Excessive channel contention.
Poor AP positioning.
Interference.
Inappropriate channel configurations.
Areas with insufficient capacity.

Not every project requires every survey method.

The appropriate assessment depends on the environment and the problems being investigated.

Capacity Planning

Do you understand the difference between coverage and capacity?

Coverage concerns whether devices can establish reliable wireless connections in the required locations.

Capacity concerns whether the network can support the expected number of devices and their applications at acceptable performance levels.

Here’s a real world example: Consider two rooms of identical size.

Room A is a storage area, occasionally accessed by one employee.

Room B is a meeting room, regularly occupied by 20 people using laptops and video conferencing.

Although both rooms occupy the same floor area, their wireless requirements are very different.

Professional Wi-Fi design considers expected usage rather than simply providing a strong signal everywhere.

The correct number of Access Points should be determined through appropriate design and assessment, not guesswork.

Should You Remove Wi-Fi Access Points to Improve Performance?

Yes, removing an unnecessary Access Point can sometimes improve Wi-Fi performance, but only when measurements demonstrate that doing so won’t create other problems.

An additional AP might contribute to unnecessary contention or provide little useful coverage or capacity.

However, switching it off could also create a coverage gap or overload neighbouring Access Points.

So how would you investigate this in your office or business?

A professional Wireless Engineer would approach this by:

Reviewing existing AP locations and configurations.
Measuring coverage and channel utilisation.
Examining how clients are distributed between APs.
Identifying potential interference or contention.
Evaluating changes to channel assignments or transmit power.
Testing whether repositioning, disabling or removing an AP improves performance.
Validating coverage and performance after changes.

As a business, you shouldn’t randomly disable Access Points or reduce transmit power without understanding the consequences.

In some environments, better channel planning or AP repositioning may resolve the issue without removing any hardware.

Frequently Asked Questions

Can too many Wi-Fi access points cause interference?

Yes. Installing too many Wi-Fi access points without appropriate channel planning can increase interference and contention. When nearby access points operate on the same channel, they may need to share the available wireless airtime. Overlapping channels can introduce additional interference. Professional Wi-Fi design helps manage these issues through appropriate access point placement, channel allocation and transmit power settings.

Can adding more access points make Wi-Fi slower?

Yes. Additional access points can make Wi-Fi slower if they increase channel contention or interference without providing useful additional capacity. However, adding access points can also improve performance when a network genuinely requires better coverage or greater capacity. The outcome depends on how the wireless network is designed and configured.

How close is too close for Wi-Fi access points?

There is no universal minimum distance between Wi-Fi access points. Appropriate spacing depends on factors including building materials, frequency bands, transmit power, antenna characteristics and expected client density.

Who Should Look After Your Office Wi-Fi: Your MSP, ISP or a Wi-Fi Specialist?

When your office Wi-Fi isn’t working properly, do you know who’s responsible for fixing it? If you’re the Office Manager, Operations Manager or Facilities Manager then it might be you that gets lumbered with all the Wi-Fi complaints. But it isn’t always obvious who is actually responsible for fixing it. Hint – It’s probably not your internal IT team.

Do you know who you should call when the Wi-Fi repeatedly goes down? Perhaps;

Your Internet Service Provider?
Your MSP or IT support company?
Your network installer?
Or a specialist Wi-Fi consultancy?

We wish there was a universal answer, but unfortunately there is not, because all of these organisations solve different types of IT problems.

An ISP is usually concerned with getting the internet connection into the building.

An MSP (Managed Service Provider) may manage computers, servers, Microsoft 365, switches, firewalls and the general IT environment.

A Wi-Fi specialist concentrates specifically on how the wireless network performs in the real physical environment.

There are several different layers involved in providing connectivity to an office, and different organisations specialise in different parts of that chain.

Our role here at Geekabit is not to replace an MSP or internal IT team. We can work alongside them when a wireless problem requires more specialist RF, survey, design or diagnostic expertise.

Why office Wi-Fi falls into a slightly awkward gap

Imagine you’re at work. The internet connection is working. The switches are online. The Access Points all appear online in their management dashboard.

Yet users are still reporting:

Slow Wi-Fi
Intermittent disconnections
Poor Teams or Zoom calls
Problems in certain rooms
Problems at particular times of day
Devices that won’t roam properly
Excellent Wi-Fi in one part of the office but poor performance elsewhere

This can become frustrating because every individual component appears to be functioning. So what is actually the problem?

Wi-Fi is unusual because part of the network exists in radio spectrum rather than cables.

A switch port can be online and an AP can show as healthy while the actual experience for somebody sitting 15 metres away can still be poor.

That is where traditional IT monitoring can have limitations.

What does your ISP actually look after?

An Internet Service Provider generally provides:

Fibre, leased line or broadband connectivity
The connection between the premises and the internet
An ISP-provided router
Public IP addressing
Sometimes DNS or related services
Fault diagnosis relating to the external internet connection

If the entire office loses internet connectivity, the ISP may therefore be exactly the right organisation to contact.

However, remember that internet and Wi-Fi are not the same thing.

A business can have a perfectly healthy 1Gbps internet connection, while somebody in a meeting room has a terrible wireless connection.

If the internet circuit is performing correctly, changing broadband provider or increasing the headline connection speed may do nothing to solve the underlying Wi-Fi problem.

For example: A laptop communicates wirelessly with an Access Point. That AP connects through Ethernet and switches before traffic eventually reaches the internet connection.

There are therefore several places where performance can deteriorate before the traffic ever reaches the ISP.

What does an MSP or IT support company look after?

MSPs perform an extremely important role for businesses and may manage a very wide range of technology, including:

Laptops and desktops
Microsoft 365
User accounts
Cybersecurity
Servers
Backups
Firewalls
Switches
VPNs
Printers
Software
General IT support
Sometimes Wi-Fi infrastructure

Many MSPs are perfectly capable of configuring and maintaining business wireless systems.

However, Wi-Fi is only one part of a very large technology estate that an MSP may be responsible for.

There is a difference between managing Wi-Fi equipment and specialising in wireless networking and RF engineering.

An MSP may be able to see that:

An AP is online
Clients are connected
Firmware is current
A switch port is operational
The internet connection is working

But persistent problems can sometimes require investigation of what is actually happening in the RF environment.

This is not a criticism of MSPs. We all have our specialisms and place in the chain.

In the same way that an MSP might bring in a specialist for structured cabling, penetration testing or a complex telephony project, wireless networking can also sometimes benefit from specialist expertise.

So what does a Wi-Fi specialist do differently?

A Wi-Fi specialist concentrates specifically on the wireless environment and the infrastructure supporting it.

An investigation into unreliable Wi-Fi goes considerably further than just checking whether Access Points are online.

Depending on the Wi-FI problem, Geekabit may investigate:

RF coverage

Where does usable Wi-Fi coverage actually exist?
Are there coverage holes?
Is the signal reaching areas from the APs that were intended to serve them?
Are users connecting to distant APs because there isn’t one appropriately located nearby?

Signal-to-noise ratio

SNR is the difference between the power of your wireless signal (RSSI) and the ambient background noise, measured in decibels (dB). Just having a detectable signal isn’t sufficient.

The useful signal needs to be sufficiently stronger than the surrounding noise for reliable communication.

Channel utilisation

How busy are the Wi-Fi channels?
Are neighbouring networks competing for airtime?
Are Access Points using unnecessarily wide channels?
Are multiple APs competing with each other?

This can be particularly relevant in dense London office environments where many other businesses may operate wireless networks nearby.

Non-Wi-Fi interference

A specialist can use spectrum analysis to investigate radio activity that may not appear in a normal Wi-Fi management dashboard.

Not everything using the same spectrum as Wi-Fi is necessarily another Wi-Fi access point.

Access point placement

AP placement shouldn’t simply be based on where it was easiest to run a cable. You need to consider:

Building materials
Walls
Floors
Glass
Metal
Office layout
Meeting rooms
User density
Device density

Capacity

A wireless network needs enough capacity for the number and type of devices actually using it.

A meeting room containing 20 people with laptops and phones presents a very different requirement from an empty corridor.

Roaming

Users increasingly expect laptops, phones and other devices to remain connected while moving around an office.

A specialist can investigate whether AP placement, power levels and network configuration are helping or hindering roaming.

Specialist equipment matters

The Wi-Fi engineers here at Geekabit do a lot more than basic IT troubleshooting. We look at Wi-Fi problems, ask the diagnostic questions needed to identify the issue, and use different tools to find the solution.

A professional Wi-Fi investigation might involve:

Wireless site survey equipment
Spectrum analysis
Wi-Fi packet/connection analysis
RF planning software
Ethernet cable testing
Network performance testing
Client association analysis
Continuous monitoring where intermittent problems need to be captured over time

Geekabit uses specialist professional tools including platforms such as Hamina as part of wireless surveys, planning and analysis.

Diagnosing wireless performance issues requires specific measurement rather than guesswork.

A phone showing three Wi-Fi bars is not a wireless survey.

Why Wi-Fi problems can be difficult to diagnose remotely

Many of our London based clients are businesses that already have remote IT support.

Remote monitoring is extremely useful and can identify many network problems.

However, some wireless problems are inherently physical. For example:

A newly installed partition changes RF propagation
A meeting room becomes heavily occupied
Furniture or storage changes
An AP is installed in a poor location
Radio interference appears intermittently
Neighbouring businesses change their wireless networks
Users are connecting to an AP on another floor
Building materials attenuate the signal
Device density has increased since the original Wi-Fi installation

Some of these problems cannot be fully understood from an online/offline indicator in a cloud dashboard.

Sometimes somebody needs to visit the building and measure what is actually happening in the air.

A Wi-Fi dashboard saying “everything is healthy” doesn’t necessarily mean everything is healthy

Modern cloud-managed Wi-Fi systems provide excellent monitoring, but their dashboards shouldn’t be treated as the complete picture.

An AP can be:

Online
Connected at Gigabit Ethernet
Running current firmware
Reporting no obvious errors

And yet all while users are still experiencing poor performance.

The controller primarily knows what the infrastructure can report to it.

It doesn’t necessarily reproduce the experience of the laptop sitting in the corner of a boardroom.

This is just one of the reasons onsite surveys and measurements remain valuable.

What if the problem isn’t actually Wi-Fi?

Here at Geekabit, we don’t approach every problem assuming Wi-Fi must be responsible.

A proper investigation may discover problems involving:

Ethernet cabling
Switch ports
Fast Ethernet rather than Gigabit links
VLAN configuration
DHCP
DNS
Internet connectivity
PoE
Client devices
Application performance

The objective is always to identify the fault rather than sell unnecessary Wi-Fi hardware.

Sometimes the most useful outcome of a Wi-Fi investigation is proving that Wi-Fi isn’t the problem.

That evidence can then help the MSP, ISP or internal IT team investigate the correct part of the network.

Should a Wi-Fi specialist replace your MSP?

Usually, no.

Our Wi-Fi engineers here at Geekabit aren’t trying to become your company’s general IT helpdesk.

If your business already has a good MSP or internal IT department, you should continue letting them do what they do well.

Geekabit Wi-Fi professionals can complement them by providing specialist wireless expertise when required.

Examples of how Geekabit could work for you include:

MSP manages the overall network; Geekabit performs the wireless survey.
Internal IT manages UniFi/Meraki/Aruba/etc.; Geekabit investigates an RF problem.
MSP specifies switches and firewall; Geekabit designs AP placement and wireless coverage.
Fit-out contractor installs cabling; Geekabit specifies where AP cables should terminate.
MSP identifies persistent Wi-Fi complaints; Geekabit performs onsite spectrum analysis and diagnostics.

Our team at Geekabit can then provide findings and recommendations that the existing IT team can implement, or we can assist with implementation where appropriate.

Our Wi-Fi engineers are more than happy to work with your existing IT company, not compete with them.

When should you call the ISP?

Calling your Internet Service Provider is likely to be the right starting point when:

The whole office has lost internet access
The router cannot establish its internet connection
Broadband/leased-line performance is below the contracted service
There is an external line fault
There appears to be an ISP routing or service issue

However, if wired devices have excellent internet connectivity while Wi-Fi users are struggling, the ISP is much less likely to be the answer.

When should you call your MSP?

Your MSP is likely to be the right starting point for:

General IT support
User/device problems
Microsoft 365
Server issues
Firewall configuration
Network configuration
Security
Switch management
Routine management of existing APs

If they can identify and resolve the wireless issue, there may be no reason to involve anybody else.

When should you bring in a Wi-Fi specialist?

A Wi-Fi specialist, like the wireless engineers at Geekabit, becomes particularly useful when:

Wi-Fi problems have continued despite normal IT troubleshooting
Problems only occur in particular areas
Wi-Fi becomes unreliable when the office is busy
Meeting rooms consistently have problems
Teams/Zoom calls drop despite fast internet
Users remain connected but performance becomes poor
Problems are intermittent and difficult to reproduce
Adding access points hasn’t solved the problem
Nobody knows whether the problem is interference, coverage or capacity
You’re moving into a new office
You’re redesigning or fitting out an existing office
You need evidence about what is actually happening in the RF environment
You want an independent assessment of an existing wireless network

London offices present particular Wi-Fi challenges

From working with different clients across London, we see that many London offices occupy:

Multi-tenant buildings
Converted buildings
Older buildings with thick internal structures
Modern offices with extensive glass and metal
Shared office developments
High-density commercial areas

Businesses may have little control over the RF environment outside their own premises.

An office could potentially have many neighbouring wireless networks operating above, below and alongside it.

This makes proper RF planning and measurement particularly valuable.

We’re not saying that every London office is automatically a terrible RF environment.

However, dense commercial buildings can present additional challenges and this is a common occurrence for London based businesses.

Geekabit’s approach

Geekabit specialises in Wi-Fi and networking, rather than providing generic outsourced IT support.

For businesses based in London and the South, we can provide services including:

Wi-Fi troubleshooting
Wireless site surveys
Spectrum analysis
Wi-Fi design
RF planning
Network Health Checks
Access point placement and optimisation
Network and cabling diagnostics

Our approach is always:

Measure → Diagnose → Recommend → Fix

Rather than just ‘buy more equipment.’

Our expert Wi-Fi engineers here at Geekabit can work directly with you and your business, alongside your internal IT team, or in partnership with your existing MSP.

Conclusion

Your ISP, MSP and Wi-Fi specialist don’t necessarily compete with each other. They solve different parts of the connectivity puzzle.

If your internet connection has failed, contact your ISP.

If you have a general IT or network problem, your MSP may be the best starting point.

But when persistent wireless problems require an understanding of coverage, capacity, interference, RF behaviour or the physical office environment, then specialist Wi-Fi expertise can provide another level of diagnosis.

For businesses in London and across the South, Geekabit provides independent Wi-Fi surveys, troubleshooting and network health checks — and we’re happy to work alongside your existing MSP or IT team.

Still being told your office Wi-Fi looks fine when your users say otherwise? Talk to Geekabit about an independent Wi-Fi assessment or Network Health Check.

FAQs

Is Wi-Fi normally the responsibility of an MSP?

It can be. Many MSPs install, configure and manage business Wi-Fi as part of their wider IT services. However, wireless networking is a specialist discipline involving radio frequency design, coverage, capacity and interference. If a persistent problem cannot be identified through normal network monitoring and troubleshooting, a specialist wireless survey or RF investigation can help identify what is happening in the physical environment.

What’s the difference between an ISP and a Wi-Fi provider?

An Internet Service Provider supplies the connection that brings internet connectivity into your premises. Your Wi-Fi network distributes network connectivity wirelessly around the building. It is therefore possible to have an extremely fast and reliable internet connection but poor Wi-Fi inside the office. Changing ISP won’t necessarily solve an internal wireless problem.

Why does our IT company say the Wi-Fi is fine when staff still have problems?

The access points and network infrastructure may appear healthy from a management dashboard while users still experience problems with coverage, interference, congestion, roaming or capacity. Some wireless problems require onsite measurements to understand what a client device is actually experiencing in a particular location.

Do I need a Wi-Fi specialist if I already have an MSP?

Not necessarily. Your MSP may be perfectly capable of resolving the issue. A specialist becomes useful when a problem requires more detailed wireless surveying, RF analysis, spectrum analysis or Wi-Fi design. Geekabit can work alongside an existing MSP rather than replacing them.

What does a professional Wi-Fi survey actually measure?

Depending on the type of survey, it can assess factors including signal strength, signal-to-noise ratio, coverage, channel utilisation, interference, AP placement and wireless capacity. The objective is to build evidence about how the wireless network actually performs throughout the premises rather than relying solely on AP status information.

Can neighbouring businesses affect our office Wi-Fi?

Yes. Wi-Fi uses shared radio spectrum, so networks in neighbouring offices can contribute to channel utilisation and contention. This can be particularly relevant in dense multi-tenant office buildings. A professional survey can help establish what other wireless activity is present and whether it is materially affecting your network.

Can you investigate Wi-Fi interference?

Yes. Geekabit can use wireless survey and spectrum-analysis tools to investigate RF conditions and identify patterns that may be contributing to poor wireless performance. Importantly, not all radio activity affecting Wi-Fi will necessarily appear as another Wi-Fi network in a standard network scan.

Can you tell if the problem is Wi-Fi or our broadband connection?

That should be one of the objectives of troubleshooting. Testing the wired network, internet connection and wireless environment can help isolate where performance deteriorates. A slow application does not automatically mean the Wi-Fi is responsible, just as a fast broadband speed test doesn’t prove that the wireless network is healthy.

Can you work with our existing IT company?

Yes. Geekabit can work alongside an existing MSP, IT support provider or internal IT department. We can investigate the wireless environment and provide findings and recommendations for the existing IT team to implement, or assist with the remedial work where required.

Do you have to replace our existing Wi-Fi equipment?

No. Replacement should not be the default recommendation. Some problems can be resolved through configuration changes, AP repositioning, channel planning, cabling repairs or other changes to the existing network. The first objective is to understand the problem and then determine the appropriate solution.

When should we consider a specialist Wi-Fi assessment?

Consider specialist assistance when wireless problems are persistent, intermittent, limited to particular areas, worse during busy periods, affecting meetings or voice/video calls, or have continued despite normal IT troubleshooting. A survey is also useful before an office move or fit-out because it allows the wireless network to be designed before AP and cabling locations become fixed.

Does Geekabit provide Wi-Fi services in London?

Yes. Geekabit provides specialist business Wi-Fi services for organisations in London and the South East, including Wi-Fi surveys, troubleshooting, RF analysis, wireless design and Network Health Checks. We can work directly with businesses or alongside their existing IT providers.

Business Network Business Wi-Fi Wi-Fi Wi-Fi Design Wi-Fi for Business Wi-Fi Help Wi-Fi Interference Wi-Fi Issues Wi-Fi Problems Wi-Fi Site Survey Wireless Network Wireless Technology

Why Does My Wi-Fi Keep Dropping Out Even Though the Signal Is Strong?

We’ve said it before, and we’ll say it again for the people in the back – A strong Wi-Fi signal does not necessarily mean a reliable Wi-Fi connection.

You can have full bars of Wi-Fi signal but still be experiencing:

Dropped Teams/ Zoom calls
Slow or intermittent internet
Applications disconnecting
Devices repeatedly reconnecting
Poor voice quality
High latency
Bluetooth problems occurring at the same time

The reliability of Wi-Fi depends on a lot more than just the strength of the signal. We unfortunately see many clients where they’ve tried to fix the problem by adding another Access Point – But this rarely works. Intermittent Wi-Fi problems require measurement and diagnosis to identify exactly what the problems are and how best to fix them. Throwing in another Access Point can cause more issues than they fix if not done correctly.

Here at Geekabit, we specialise in investigating the RF environment of your wider network, rather than just assuming that every reported Wi-Fi problem is caused by weak coverage. News Flash: It’s often not.

Does this sound like one of your employees?

An employee comes to the IT Manager and complains that their Wi-Fi keeps dropping out, despite their laptop showing 3 or 4 bars of signal.

Surely then, the Wi-Fi can’t be the problem? Wrong! We can see the logic, but hopefully your IT Manager gets a little more curious than either wrongly assuming that the Wi-Fi can’t be the problem, or just installing another Access Point in the vicinity of the employee experiencing problems.

But signal strength is only one measurement of wireless performance.

A reliable Wi-Fi connection depends on:

Interference
Noise
Channel utilisation
Access Point placement
Network design
Client behaviour
The infrastructure behind the Wi-Fi

What do the Wi-Fi bars actually tell you?

The strength of a wireless signal when a device receives it is measured in Received Signal Strength Indicator, or RSSI.

The signal bars you see on your device show how strongly it can ‘hear’ the Access Point.

What these signal bars don’t tell you, is:

How busy the channel is
Whether another transmitter is interfering
Whether packets are repeatedly being retransmitted
Whether the access point is overloaded
Whether the device has chosen the best AP
Whether DHCP or DNS is working properly
Whether the internet connection itself is stable.

Think of it as being a bit like someone talking loudly in a crowded room – You might be able to hear their voice, but struggle to understand what they are actually saying.

What people sometimes forget or don’t realise, is that Wi-Fi is two-way communication. Hearing the AP doesn’t automatically mean that the

Also mention that Wi-Fi is two-way communication. A device hearing the AP strongly doesn’t automatically mean the AP can hear the client device equally well.

Interference can cause problems despite excellent signal

RF or Radio Frequency is what powers wireless technologies like Wi-Fi, Bluetooth, mobile phones, radio/ TV broadcasting, and radar.

Wi-Fi operates in this shared radio spectrum, meaning that interference can occur – Both through the competition for airtime and physical blocks to the waves.

This means that the frequencies used by Wi-Fi can be interfered with by other Wi-Fi devices as well as non-Wi-Fi devices. Things that can cause interference are:

Bluetooth devices (although it’s important to point out that not every Bluetooth device destroys Wi-Fi – Modern systems are designed to co-exist. But in congested or unusual RF environments, interference can be relevant)
Wireless audio/ video equipment
Some IoT equipment
Microwaves
Cordless/ wireless equipment
Specialist industrial or building equipment
The buildings themselves

Remember that interference can be intermittent – An employee might complain to the IT Manager at 10am that there’s a problem, but by the time they have a chance to investigate it at 2pm, it’s apparently disappeared.

Wi-Fi Scanner vs Spectrum Analyser

It’s important to note the distinction between these 2 Wi-Fi tools.

A conventional Wi-Fi Scanner can see Wi-Fi networks and Access Points. It cannot necessarily tell you what non-Wi-Fi radio activity is occupying the spectrum.

Spectrum Analysis examines RF energy itself. This can reveal interference that wouldn’t appear as another SSID.

Professional troubleshooting of Wi-Fi problems would likely therefore combine Wi-Fi Analysis with Spectrum Analysis.

Your device may be connected to the wrong access point

Did you know that a device doesn’t necessarily connect to the AP that’s physically nearest? You do now.

Your device ultimately makes many roaming decisions by itself. A laptop can remain attached to an AP further away, when there is a better one available.

It’s also worth noting that the way a building is constructed can make physical distance misleading. For example, an AP that appears close by on a floor plan, might actually be:

Upstairs
Through a reinforced floor
Behind several walls
Around a corridor
Serving users from an unintended location

Remember that a strong enough signal for connectivity, doesn’t necessarily mean it’s sufficient for a consistently good user experience.

Proper AP placement really matters.

Too many access points can also cause problems

If you’re experiencing Wi-Fi problems, adding more AP’s isn’t necessarily the solution. You can read more about that here.

The problem may actually be with the network design. Poorly designed networks can have:

Excessive transmit power
Overlapping coverage
Too many AP’s sharing channels
Poor channel allocation

Badly configured APs can actually increase contention.

Wi-Fi networks should be designed around coverage and capacity, rather than simply filling a building with radios. .

Channel width matters — particularly on 2.4 GHz

A Wi-Fi channel width of 20 MHz provides a narrower, more stable connection with less interference, while 40 MHz bonds two channels together to double your theoretical speed, but at the cost of higher susceptibility to interference.

The 2.4 GHz band has very limited usable spectrum. Using unnecessarily wide channels consumes more of it.

In busy environments, 40 MHz channels on 2.4 GHz can contribute to poor coexistence and increased contention.

For many business deployments, 20 MHz channels on 2.4 GHz are the sensible choice.

Wider isn’t automatically faster in a real-world environment.

It’s important when channel planning that your IT Manager considers neighbouring networks and the actual RF environment.

The problem might not actually be Wi-Fi

Picture this. One of your employees rings the IT Manager and says “The Wi-Fi went down!”

This user can be experiencing a failure anywhere along this chain:

Laptop → Wi-Fi → AP → switch → router/firewall → ISP → internet service

The potential cause of this failure could be:

Failing or incorrectly configured network switches
Ethernet links negotiating at the wrong speed
Damaged cabling
PoE problems
VLAN/configuration errors
DHCP exhaustion or slow DHCP responses
DNS failures
Gateway/router problems
ISP instability
Packet loss upstream
Internet connection congestion

Unfortunately, just replacing APs isn’t going to fix any of these problems.

Why intermittent Wi-Fi problems are difficult to diagnose

Perhaps the only good thing about persistent Wi-Fi faults is that they are relatively easy to diagnose because they’re still present when the Wireless Engineer arrives.

Intermittent faults on the other hand, require evidence.

A short visit from a Wi-Fi Engineer might find a network that appears to be completely healthy. This is why it’s important to engage a wi-Fi specialist who can conduct a useful investigation that includes:

Spectrum analysis
Wi-Fi scanning
Channel utilisation measurements
AP/controller logs
Roaming information
Latency and packet-loss testing
Wired-network testing
Longer-term monitoring

Where appropriate, leaving a monitoring device onsite can help establish exactly when failures occur and whether the LAN, DNS, gateway or internet connection is affected simultaneously.

The aim of our expert Wi-Fi Engineers is to correlate your user’s reported experience with measurable network behaviour. Then we can get to work in providing the fix.

Why Bluetooth dropping out at the same time can be an important clue

Bluetooth also operates in the 2.4 GHz spectrum.

If users report both Wi-Fi and Bluetooth problems in a particular location, that is very useful diagnostic information.

Whilst it doesn’t automatically prove RF interference, it does give an engineer a reason to investigate the local 2.4 GHz spectrum rather than concentrating solely on the Wi-Fi configuration.

This is an excellent example of why asking users exactly what they experience can be as important as looking at the controller dashboard.

How should a business investigate Wi-Fi that keeps disconnecting?

If your business is experiencing intermittent Wi-Fi problems, then it’s time for your IT Manager to get curious and start recording some data. Does the problem affect one user, one room, one AP or the whole building? Start making a log of:

Where the problem happens
When it happens
Which devices are affected
Whether wired devices are affected
Whether Bluetooth is affected
Whether users still show strong Wi-Fi signal;
Whether it happens during particularly busy periods.

Don’t be tempted to try random things before getting curious. The following actions can mask the underlying fault or even make the RF environment worse.

Things to avoid doing:

Rebooting everything repeatedly
Installing additional APs
Turning every AP’s transmit power to maximum
Widening channels in pursuit of higher headline speeds

What does a professional Wi-Fi investigation involve?

We sometimes see clients assuming they know what the Wi-Fi problem is and trying what they think is the obvious solution. But you need to start with the reported symptoms and get curious about what the cause could be.

A professional Wi-Fi investigation starts with the reported symptoms and uses them to lead an examination of the existing Wi-Fi design and configuration.

A specialist Wi-Fi Engineer will measure the RF environment and look for both Wi-Fi and non Wi-Fi interference. They will assess channel utilisation and channel planning.

Access Point placement will be checked, alongside actual client associations.

The wired infrastructure will also be examined as well as the internet path where relevant.

All of the data from these investigations leads to the Geekabit team making evidence-based recommendations. This could be new hardware, or some configuration changes to your existing network. Sometimes it’s as simple as repositioning equipment or fixing something elsewhere in the network.

Our expert Wi-Fi Engineers here at Geekabit will always find the cause of your Wi-Fi problems before recommending the cure. You can contact our friendly team to find out more.

Remember: Strong Wi-Fi signal doesn’t guarantee good Wi-Fi

Reliable wireless networks depend on clean spectrum, sensible RF design, appropriate AP placement, sufficient capacity and a healthy network behind the Access Points.

If your business is experiencing repeated Wi-Fi dropouts, the most useful first step isn’t necessarily buying more equipment. It’s getting curious and establishing what is actually failing.

If you need any help with business Wi-Fi troubleshooting or you are interested in a Network Health Check for your business, please don’t hesitate to get in touch with our team here at Geekabit. Our professional Wi-Fi Engineers are experts in their field and ready to help make your Wi-Fi network more reliable so your business operations run smoothly.

FAQs

Why does my Wi-Fi keep disconnecting when I have full signal?

Full Wi-Fi signal generally means your device can receive a strong signal from the access point. It doesn’t tell you whether the radio channel is congested, whether interference is present, whether packets are being lost or whether another part of the network is failing. A device can therefore display full Wi-Fi bars while still experiencing an unreliable connection.

Can Wi-Fi interference cause devices to disconnect?

Yes. Wi-Fi and other radio transmissions can interfere or compete for airtime, particularly in busy environments. This can result in reduced throughput, increased latency and retransmissions and, in more severe cases, unreliable connections. Spectrum analysis can help identify RF activity that a normal Wi-Fi scanner may not detect.

Can Bluetooth interfere with Wi-Fi?

Bluetooth and 2.4 GHz Wi-Fi share the same general frequency band and are designed with coexistence mechanisms. Usually they operate alongside each other successfully. However, heavy or unusual 2.4 GHz RF activity can affect wireless performance. If Bluetooth and Wi-Fi devices experience problems simultaneously in the same location, it can be a useful reason to investigate the local RF environment.

Why does my Wi-Fi only drop out in one room?

A location-specific problem can be caused by AP placement, building materials, interference, channel conditions or the device connecting to an AP that isn’t ideally positioned to serve that room. Measuring the network from the affected location is often more useful than relying solely on an AP controller or floor plan.

Will adding another Wi-Fi access point stop dropouts?

Not necessarily. Another AP can improve coverage where signal is genuinely inadequate, but it won’t solve problems caused by interference, DHCP, DNS, cabling, switching, broadband or poor configuration. Adding APs without considering channel planning can sometimes make wireless performance worse.

Should businesses use 20 MHz or 40 MHz channels on 2.4 GHz?

In many business environments, 20 MHz channels are preferable on 2.4 GHz because the band has limited spectrum available. Using 40 MHz channels consumes considerably more of that spectrum and can make effective channel planning and coexistence with nearby networks more difficult.

What’s the difference between Wi-Fi analysis and spectrum analysis?

Wi-Fi analysis examines Wi-Fi networks, access points, channels and related protocol information. Spectrum analysis looks at radio-frequency energy across the band, which can expose interference that isn’t generated by Wi-Fi equipment. Professional troubleshooting may use both because a Wi-Fi scanner alone cannot identify every source of RF activity.

How can I tell whether the problem is Wi-Fi or my internet connection?

Testing connectivity at several points can help isolate the problem. An engineer might test communication to the local gateway alongside DNS, external internet connectivity, packet loss and latency. Comparing wired and wireless devices can also help establish whether the fault is within the Wi-Fi network or further upstream.

Why does office Wi-Fi work perfectly sometimes and badly at other times?

Changing numbers of users, channel utilisation, neighbouring networks, intermittent RF interference and internet utilisation can all cause performance to vary throughout the day. Longer-term monitoring and spectrum analysis can be particularly useful when the fault isn’t present during an engineer’s visit.

What information should I record before reporting an intermittent Wi-Fi problem?

Record when and where the problem occurs, which devices are affected, whether the device still shows Wi-Fi signal, what application was being used and whether wired or Bluetooth devices experience problems at the same time. Patterns in this information can substantially narrow down the potential causes.

Business Network Ubiquiti Ubiquiti UniFi Wi-Fi Wi-Fi Advice Wi-Fi Design Wi-Fi for Business Wi-Fi Help Wi-Fi Issues Wi-Fi Problems Wi-Fi Site Survey Wireless Network

UniFi Wi-Fi for Business: Is Ubiquiti Good Enough for a Professional Network?

Here at Geekabit, we talk a lot about Ubiquiti and use their hardware for many of our business clients. Ubiquiti UniFi has become extremely popular, being used in home networks as well as offices, hospitals, retail and other commercial environments.

With attractive pricing and a single management ecosystem, it’s an inviting choice when it comes to planning a network. But we’re commonly asked this question: Is UniFi really suitable for a professional business network?

The short answer is Yes, it’s absolutely suitable in the right environment. But professional Wi-Fi is about far more than just the logo on your Access Point. Proper design, configuration and ongoing management are critical for your business network to work reliably and efficiently.

What Is Ubiquiti UniFi?

Ubiquiti UniFi is an integrated networking ecosystem. Products in a Ubiquiti network include:

Wireless access points
Network switches
Gateways and firewalls
Controllers
Cameras and security
Other network infrastructure

It has a central management interface and is suitable for networks ranging from relatively small deployments to substantial multi-AP installations.

Is UniFi Suitable for Business Wi-Fi?

Yes. UniFi can be an excellent business Wi-Fi platform when appropriately designed, specified and managed.

A Ubiquiti UniFi network could work well in various business environments, including:

Offices
Retail
Hospitality
Warehouses
Schools and education campuses
Multi-site businesses
Guest Wi-Fi environments

Individual suitability should always be assessed against your business’ specific operational requirements.

Why Is UniFi Popular with Businesses?

There are a number of reasons why Ubiquiti Uni is a popular option for business networks. It’s an attractive solution for any organisation wanting a cohesive network, rather than a mish-mash of unrelated products.

In our experience here at Geekabit, our clients and businesses opt for UniFi when choosing their business network due to:

Competitive hardware pricing.
Broad hardware ecosystem.
Centralised management.
Strong visibility into network devices.
VLAN/ network capabilities.
Guest Wi-Fi functionality.
Remote management.
Wide AP range.

Is UniFi ‘Enterprise Grade’?

‘Enterprise grade’ isn’t exactly a technical standard that us Wi-Fi experts tend to use. It’s also important to recognise that different organisations can have very different requirements.

The reason why UniFi is often the ‘go to’ option is that it can comfortably support many professional and business requirements.

Organisations that are very large, and/or have mission-critical requirements may be more suited to alternative options like Cisco, Aruba or Ruckus. These types of environments could include requirements like:

Vendor support SLAs
Advanced security
Regulatory requirements
Hardware redundancy
Change control
Integration
Very large-scale management

Our Wi-Fi engineers here at Geekabit are committed to matching the right technology to each specific business case. That means that we don’t automatically assume one ecosystem (like UniFi) is universally superior. We make sure that any platform selection for a business follows their specific requirements and is the best choice for their needs.

UniFi Hardware Isn’t the Same Thing as Good Wi-Fi

Unfortunately, it’s not as easy as just buying excellent APs – That alone doesn’t guarantee you’ll have an excellent wireless network. Fortunately, engaging expert Wi-Fi professionals like Geekabit means that your network is designed around your working environment.

Excellent APs but poorly deployed can still cause your network to suffer. You might experience:

Dead spots
Interference

Which UniFi Access Point Should a Business Choose?

We could make you a whole list of APs here, but you don’t need us for a catalogue of products. What we can explain however, is what things to consider when you’re choosing an AP. Considerations to make when selecting an AP include:

Wi-Fi generation – Are you going for Wi-Fi 7 yet? What generation are your user devices? Will all your hardware be the same generation?
Client density – How many clients will be accessing your AP at once time / location?
Required bands – What frequency bands will you be using?
Coverage requirements – Where do you need Wi-Fi coverage?
Mounting position – Do you know where the best mounting position is? And where to avoid mounting APs?
Indoor/ outdoor – Do you need to cover an outdoor area as well as indoors?
Ethernet uplink – Where will there be a connection to Ethernet?
PoE requirements – Will you be needing to pass power as well as data over Ethernet connections?

It’s worth remembering that a higher model number or more expensive AP doesn’t automatically mean it’s a better option for every location. Your AP selection should always happen after you have identified requirements and done the RF planning.

How Many UniFi Access Points Does My Business Need?

As much as we wish there was a simplistic square-metre rule, there just isn’t unfortunately.

The number of APs your business needs depends on various factors, including:

The building materials used in your office
Client density
Applications
Coverage
Capacity
Interference
Roaming
High-Density areas

Good, successful Wi-Fi design should always be based on a Wi-Fi survey that has determined the best quantity and placement for APs in your specific business environment.

What About UniFi Switching and PoE?

Your wireless network is only as reliable as the infrastructure underneath it.

UniFi APs require appropriate Ethernet connectivity and, in most business installations, PoE (Power over Ethernet).

When defining the exact technical requirements and features you need to meet with a switch, you should consider:

The total number of APs and other PoE devices.
Total available PoE power budget — not simply the number of PoE ports.
PoE / PoE+ / PoE++ requirements of individual devices.
1 GbE versus 2.5 GbE or faster uplinks, particularly with newer Wi-Fi 7 APs.
Required number of switch ports.
SFP/SFP+ requirements between switches or buildings.
Future expansion.

A PoE switch that doesn’t meet your specifications can lead to:

APs failing to start correctly.
Devices operating with restricted functionality.
Intermittent behaviour.
Problems appearing when additional equipment is connected.

You should also consider any existing structured cabling.

A new UniFi AP won’t fix:

Damaged Ethernet cabling.
Poor terminations.
Links negotiating at 100 Mbps rather than 1 GbE.
Inappropriate legacy switches.

A professional installation should always test the whole path from:

Client → AP → switch → gateway → internet

rather than treating the AP in isolation.

Do You Need a UniFi Cloud Gateway or Controller?

First let’s explain these UniFi devices.

A UniFi Cloud Gateaway is an all-in-one hardware device by Ubiquiti that acts as your home or business network router and firewall while hosting the built-in software controller used to manage your UniFi equipment.

A UniFi Controller (now officially called the UniFi Network Application) is a centralized management platform created by Ubiquiti to configure, monitor, and control your UniFi networking hardware from a single dashboard.

Depending on the installation, this can be hosted on:

A UniFi Cloud Gateway/ Console.
Suitable dedicated UniFi hardware.
A self-hosted environment where appropriate.

A business should consider:

Who manages the controller.
Who has administrator access.
How configuration backups are handled.
Software/ firmware update policy.
Remote support requirements.
What happens if the controller/ gateway fails.

It’s worth remembering that loss of the management interface does not necessarily mean the Wi-Fi network immediately stops functioning. But gateways/ controllers can provide other critical network services, so architecture matters.

Professional deployment should always avoid situations where nobody knows the admin credentials or who owns/ manages the network!

Can UniFi Provide Guest Wi-Fi for a Business?

Yes, Ubiquiti UniFi can provide Guest Wi-Fi for a business. UniFi can support separate guest networks and different approaches to guest authentication and access.

This means that businesses can separate:

Staff devices.
Guest devices.
IoT equipment.
Other operational systems.

VLANs and appropriate firewall/ network policies can help keep guest traffic separated from internal resources.

Your Guest Wi-Fi requirements may include:

Captive portal.
Terms of use.
Authentication.
Branded landing pages.
User data capture
Marketing integrations.

Where personal data is collected, businesses also need to consider:

UK GDPR policies.
Privacy notices.
Getting consent where appropriate to comply with laws.
Data retention.
Third-party integrations.

Remember that “Guest” SSID alone isn’t a complete guest-network security strategy.

Is UniFi Secure Enough for a Business?

It would be silly of us to claim that any vendor is automatically secure, as that is not the case.

However, UniFi provides the tools needed to build secure networks for many business environments.

The security of your network depends heavily upon configuration and management.

For a safe and secure Wi-Fi network it’s important to consider:

Strong administrator authentication.
MFA where available.
Appropriate firewall rules.
VLAN/network segmentation
Secure Wi-Fi authentication.
Guest isolation
Firmware/software updates.
Restricting unnecessary management access.
Maintaining backups.

A professionally configured UniFi network can be very different from an out-of-the-box installation using largely default settings.

Can UniFi Handle Multiple Offices or Sites?

UniFi can be particularly attractive for businesses with multiple locations.

Centralised visibility can make it easier to monitor:

APs.
Switches.
Gateways.
Connected clients.
Network health.

Standardised configurations can simplify supporting multiple sites and remote troubleshooting can reduce unnecessary site visits.

But, network architecture should still reflect each individual site’s requirements. Don’t assume that a configuration that works in one office should simply be copied to every other building as RF conditions are inherently site-specific and what works for one premises, might not work for another.

Is UniFi Good for Large or High-Density Wi-Fi Networks?

Potentially, yes — but this is where RF design becomes increasingly important. High-density Wi-Fi isn’t automatically solved by simply installing lots of APs.

For example, environments like:

Busy offices.
Conference/event spaces.
Hospitality.
Education.
Warehouses.
Public-facing venues.

You still need to consider:

Number of simultaneous clients.
Device capabilities.
Airtime utilisation.
Channel reuse.
Channel widths.
Transmit power.
AP placement.
Backhaul capacity.

Capacity planning can become more important than simply achieving signal coverage. It’s a fine balance, and one that can be struck by engaging a Wi-Fi professional. Our expert Wi-Fi engineers here at Geekabit are wireless specialists and have the credentials to make sure that both your coverage and capacity needs are met, from small business networks to large, high-density business networks.

What Are the Downsides of UniFi for Business?

This article shouldn’t read like a Ubiquiti fan page. We sing their praises, and rightly so, but it isn’t the right solution for everyone and it’s part of our job here at Geekabit to make sure that we match the right hardware to your specific network requirements. We won’t automatically reach for Ubiquiti every time.

We always make the following considerations matching hardware to business network needs:

Support model compared with some traditional enterprise vendors.
Firmware/ software changes need to be managed appropriately.
Different generations of UniFi hardware have different capabilities.
Advanced enterprise requirements may require alternative platforms.
Organisations with strict vendor SLAs or specific compliance requirements should assess those requirements carefully.

Also price. Hardware cost shouldn’t be the sole basis for selecting a network platform.

For some organisations Cisco, HPE Aruba, Ruckus or another enterprise platform may be more appropriate.

Conversely, paying substantially more for an enterprise platform doesn’t automatically create better Wi-Fi.

Design, configuration and ongoing management remain fundamental regardless of vendor.

UniFi vs Traditional Enterprise Wi-Fi

When you’re comparing UniFi with other traditional enterprise Wi-Fi, you should be considering some of the following:

Hardware cost.
Licensing/subscription model.
Central management.
Product range.
Vendor support.
Advanced enterprise features.
Ease of deployment.
Multi-site management.
Suitability for SMEs.
Suitability for large/complex enterprise environments.

The answer you’re looking for will always depend on your organisation’s needs rather than merely brand reputation.

Should I Replace My Existing Business Wi-Fi with UniFi?

The answer to this question should always start with understanding why the existing network isn’t meeting your requirements.

Don’t replace functioning infrastructure purely because UniFi has a newer AP available.

You will need to assess the following:

Current APs
Coverage.
Capacity.
RF environment.
Cabling.
Switches.
PoE availability.
Gateway/firewall.
Internet connection.
Current and future client devices.

In some scenarios, reconfiguration may solve your problems. Other times, you may need additional or repositioned APs to help solve the Wi-Fi issues.

Of course, in some situations, a complete redesign may make more commercial sense. You might find our recent article “Do I Need More Wi-Fi Access Points – or Better Wi-Fi Design?” in this case.

Do I Need a Wi-Fi Survey Before Installing UniFi?

If your business is a small, relatively simple site, then your Wi-Fi network requirements could be straightforward.

For larger, complex or business-critical environments, professional Wi-Fi Design and a Site Survey can substantially reduce guesswork and improve the outcomes of your Wi-Fi network.

Wi-Fi Surveys and Design can help establish:

Appropriate AP quantity.
AP locations.
Expected coverage.
Areas requiring additional capacity.
Effects of walls/building materials.
Existing interference.
Appropriate channels/channel widths.

Post-installation validation can confirm whether the finished network meets its objectives. The objective is a network that works reliably for your people using it.

Already Have UniFi but Experiencing Wi-Fi Problems?

Here at Geekabit, we find that many businesses already have perfectly capable UniFi equipment, but remain unhappy with their Wi-Fi.

Some of the most common problems our Geekabit engineers encounter in these situations are:

Poor AP placement.
Automatic settings not appropriate for the environment.
Excessive transmit power.
Poor channel allocation.
Inappropriate channel widths.
Coverage gaps.
Too many APs.
Insufficient AP capacity.
PoE issues.
Ethernet faults.
Incorrect VLAN/network configuration.
Legacy equipment mixed into newer deployments.

Automatically just replacing everything shouldn’t be the first response. You need to get curious first!

And our Wi-Fi experts here at Geekabit love to get curious about a Wi-Fi network not performing at its optimum. A Wi-Fi network health check can establish what is actually going wrong – And how best to fix it.

So, Is Ubiquiti UniFi Good Enough for Professional Business Wi-Fi?

Yes — UniFi is suitable for professional business Wi-Fi in many environments.

It offers capable wireless hardware, switching, gateways and centralised management at a competitive cost.

But remember, simply buying UniFi equipment isn’t the same thing as designing a professional network.

A successful business Wi-Fi network depends upon:

Correct requirements.
RF design.
AP selection and placement.
Channel planning.
Correct switching and PoE.
Reliable cabling.
Security/configuration.
Monitoring and maintenance.

You shouldn’t just be asking “Is UniFi good enough?” You also need to know that your network has been designed properly.

Access Point Access Points Wi-Fi Wi-Fi Advice Wi-Fi Design Wi-Fi Help Wi-Fi Interference Wi-Fi Issues Wi-Fi Problems Wi-Fi Site Survey Wireless Network Wireless Technology WLAN

Do I Need More Wi-Fi Access Points – or Better Wi-Fi Design?

It’s a common misconception that poor Wi-Fi is caused by not having enough Access Points.

Unfortunately, businesses often assume that the solution to dead spots or unreliable connections is to buy another AP. Of course, there are occasions where it might work – But there are also times when adding another AP could make an existing Wi-Fi problem worse.

It’s important to remember that Wi-Fi performance is about coverage, capacity and RF design, not just the number of Access Points.

A specially designed network determines:

Where AP’s should be located
How they should be configured
How they interact

The aim isn’t just to have maximum signal everywhere – It’s to have a predictable, reliable wireless network. And that is where professional Wi-Fi engineers like the team here at Geekabit can help get your network working at its optimum for your business.

What Does a Wi-Fi Access Point Actually Do?

What is an Access Point?

An Access Point is a networking hardware device that helps create a wireless local area network, for example in an office or business premises. The wireless local area network (WLAN) is a computer network that connects devices together using radio waves instead of physical cables.

What does an Access Point do?

The Access Point connects wireless devices to a wired local network.

An Access Point bridges networks by plugging into a wired router or switch using an Ethernet cable and translates that wired data into a Wi-Fi signal.

They extend coverage by creating a wireless zone in areas where the main router’s Wi-Fi signal cannot reach.

Access Points act as a central hub, letting phones, laptops, and smart devices connect to the network at the same time without losing speed or stability.

They support high capacity in locations like large offices or schools. Multiple Access Points work together to handle hundreds or even thousands of users depending on the size of the venue and network.

AP’s in Business Networks

Business networks commonly have multiple AP’s working together. Devices move between AP coverage areas and need to be able to roam appropriately.

AP’s share a finite radio spectrum with neighbouring AP’s and other devices. This means that simply installing more AP’s doesn’t automatically provide more usable Wi-Fi.

Business networks commonly have multiple APs working together.
Devices move between AP coverage areas and need to roam appropriately.
AP’s share a finite radio spectrum with neighbouring APs and other devices.
Therefore, simply installing more APs doesn’t automatically provide more usable Wi-Fi.

How Many Wi-Fi Access Points Does a Business Need?

Wouldn’t it be lovely if there was a reliable formula based purely on square metres? Unfortunately there isn’t, it doesn’t work like that.

The number of Access Points that a business needs depends on:

Building size.
Building materials.
Floor layout.
Number of floors.
Number of users/devices.
Types of devices.
Applications being used.
Required speeds.
Voice/video requirements.
Existing neighbouring Wi-Fi networks.
Available wired network infrastructure.

It makes sense that different businesses in different industries with different Wi-Fi needs – Think warehouse, hotel, office, school – would need different Wi-Fi designs, despite having identical floor area on paper.

You also need to bear in mind that capacity can require additional AP’s even where signal coverage is already excellent.

What Are the Signs That I Might Need Another Access Point?

There will of course be scenarios where another Access Point would be a legitimate Wi-Fi fix. So how do you as a business recognise when you might need another Access Point?

Identifying an area with genuinely inadequate usable coverage.
Getting poor signal in rooms separated by substantial walls
Requiring coverage across additional floors
Realising some outdoor areas need Wi-Fi
Having high numbers of devices concentrated in particular locations (high density areas)
Noticing users experiencing poor performance only in particular physical areas
Having an existing AP physically incapable of providing appropriate coverage

Whilst these scenarios may well benefit from another strategically placed AP, it’s worth saying that these symptoms justify investigation. Investing in a well designed Wi-Fi network could mean you don’t waste money on unnecessary APs.

Can You Have Too Many Wi-Fi Access Points?

Simply – Yes! It is possible that having too many Access Points can cause more problems and make your WI-Fi worse rather than better.

APs share available radio spectrum. This means it’s possible that there could be co-channel interference or contention between APs. This is when more than one AP uses the exact same frequency channel at the same time, in an overlapping area.

Having too many Access Points can also cause Adjacent-channel interference where a transmission on one frequency leaks into a neighboring, overlapping frequency channel causing signal distortion.

Too many APs in one area causes excessive overlapping coverage.

Strategic channel selection helps your APs work to their most effective. Poor channel selection causes signal interference, slower speeds, and dropped connections.

Transmit power is also a strategic choice. You might think you should just set the AP to maximum power to get the best performance, however excessive transmit power can mean that APs are connecting to wireless devices inappropriately, when devices should roam and connect to a better placed AP that will provide a more reliable connection. Just because an AP is ‘shouting louder’ doesn’t mean it can provide the best connection.

Unfortunately, excellent-looking signal bars don’t always translate to efficient wireless networks and often exhibit disappointing real world performance. Dense installations should always be properly planned and installed.

Why Full Wi-Fi Signal Doesn’t Necessarily Mean Good Wi-Fi

Signal strength is only one measurement, and can be affected by various factors between the AP and the device.

We can scrutinise wireless signal in a few different ways.

RSSI (Received Signal Strength Indicator) is a measurement of how strong a wireless signal is when a device receives it. RSSI is usually shown as a negative number in decibels-milliwatts (dBm) and a value closer to 0 means a stronger signal.

SNR (Signal to Noise Ratio) is the ratio comparing the power of a desired useful signal to the power of unwanted background noise, usually measured in decibels (dB). A higher SNR means a clear, crisp signal with very little interference. A low SNR means the signal is hidden or corrupted by static and noise.

Noise and interference are unwanted radio signals or physical blocks that disrupt your wireless connection and slow down your internet.

Channel utilization is the percentage of time that a specific wireless channel is busy transmitting or receiving data, or blocked by interference. In Wi-Fi, only one device can talk on a channel at an exact millisecond, so a busy channel forces other devices to wait. This in turn lowers overall network speed and increases lag.

Regarding wireless connectivity, airtime refers to the actual duration an Access Point or client spends actively communicating data across a specific frequency.

A device can show full bars while experiencing:

Slow downloads.
High latency.
Teams/Zoom problems.
Dropouts.
Poor roaming.

Remember, Wi-Fi is two-way communication. The AP must hear the client as well as the client hearing the AP.

Access Point Placement Matters as Much as Access Point Quantity

An AP shouldn’t simply be installed wherever an Ethernet cable happens to be available.

Here are some of the poor locations our Wi-Fi engineers have discovered APs when investigating a poorly performing Wi-Fi network:

Cupboards.
Behind televisions/screens.
Inside cabinets.
Above inappropriate building materials.
At one end of a building.

Hiding APs away in cupboards aren’t the only things that can cause a wireless network to perform badly. Walls, concrete, metal, glass and building layout all affect RF differently too.

Ensuring the correct placement of Access Points can sometimes reduce the number of APs required.

Professional Wi-Fi network planning considers both coverage and capacity.

What Is Professional Wi-Fi Design?

The best Wi-Fi design starts with requirements rather than equipment.

When we investigate an office or business premises for a new or updated Wi-Fi network, our Wi-Fi engineers always determine:

Where Wi-Fi is required.
Number/ type of clients.
Critical applications.
Performance requirements.
Physical environment.

Our engineers do this by carrying out an appropriate survey which can include:

Predictive modelling.
On-site measurements.
Spectrum/RF analysis.
Validation after installation.

AP locations, channels, channel widths and power settings can then be designed accordingly, meaning your Wi-Fi network actually matches your business needs.

Don’t Forget the Wired Network

Wi-Fi networks aren’t always just about the wireless element – There is also a wired component. The Wi-Fi Access Point ultimately connects to Ethernet. This means that problems with a Wi-Fi network could potentially originate in a wired part of the network, including:

Damaged cabling.
100 Mbps links where Gigabit was expected.
Faulty termination.
Switch problems.
Insufficient PoE.
VLAN/configuration problems.
Router/firewall problems.
Internet connection itself.

Just blindly installing another AP won’t fix an underlying wired-network fault.

Should I Add Another AP or Get a Wi-Fi Survey?

If the cause of your Wi-Fi problems isn’t obvious, then it’s a good idea to diagnose the issue before purchasing more equipment.

A Wi-Fi Site Survey can identify:

Coverage gaps.
Interference.
AP placement problems.
Channel problems.
Capacity issues.
Cabling/ network issues.

Sometimes recommendations may genuinely be another AP!

Other times, your existing equipment ends up being able to perform much better simply through a redesign or reconfiguration.

Our approach here at Geekabit is always to diagnose the Wi-Fi problem first, and then prescribe the solution second.

Broadband Fibre Broadband Full Fibre Gigabit Broadband Leased Line London Wi-Fi Wi-Fi Advice Wi-Fi Help Wi-Fi Issues Wi-Fi Problems Wi-Fi Site Survey Wi-Fi Speed Test Wireless Network

Why London Offices Struggle With Wi-Fi — Even With Fast Fibre

Does this sound like your business, or perhaps a client of yours?

You’ve invested in a fast internet connection – Perhaps 500Mbps, 1Gbps or a leased line. Wired computers connected to the network perform extremely well, but staff are still continuing to report:

Slow Wi-Fi
Teams/Zoom calls dropping
Poor performance in particular meeting rooms
Laptops disconnecting or reconnecting
Devices hanging onto the wrong access point
Good Wi-Fi in one part of the office but poor performance elsewhere
Problems becoming noticeably worse when the office is busy

The in-house IT team checks the internet connection and reports that everything looks fine. And both statements can be true: The Internet connection can be excellent AND the Wi-Fi can be poor.

If your London business has recently installed fibre, leased lines or gigabit broadband, but haven’t seen the improvement you expected with the Wi-Fi then please read on.

What’s the difference between broadband / internet and Wi-Fi?

The Internet connection or broadband is the service bringing connectivity into the building. Wi-Fi is the radio network distributing that connectivity wirelessly around the office.

When you buy a faster internet connection, that only increases the potential bandwidth available at the edge of the network. It doesn’t automatically improve:

Wireless coverage
Interference
Channel utilisation
Access-point capacity
Roaming
Poor AP positioning
Network configuration

Think about it like this. Upgrading the motorway into a city doesn’t necessarily remove congestion from the streets around the destination.

Similarly, conducting a speed test beside an Access Point isn’t evidence that the entire wireless network is healthy and working to the same speed.

Why do London offices tend to be particularly difficult wireless environments?

London offices have a high density of neighbouring businesses and wireless networks. Numerous Access Points may be visible from surrounding offices. This is especially relevant in business in:

Shared office buildings
Serviced offices
Converted buildings
Multi-tenant commercial buildings;
Dense central London locations.

Wi-Fi uses shared radio spectrum. Your network doesn’t operate in isolation simply because it has its own SSID. Other wireless networks and sources of interference can affect the available airtime. The challenge is therefore often much greater than simply achieving “full bars”.

Coverage isn’t the same as capacity

An Access Point may provide a perfectly strong signal but still be overloaded or operating in a congested environment. Traditional office Wi-Fi was often designed primarily around providing coverage. Modern offices need to consider capacity as well.

50 people with laptops and phones can easily represent 100+ connected devices. Then add in:

Company tablets
Meeting-room equipment
Printers
TVs
IoT devices
Wireless presentation systems.

Wi-Fi needs to be designed around how the space is actually used, not merely the size of the floorplan.

The Meeting Room Problem

The Meeting Room provides us with a particularly good real-world example of the kind of Wi-Fi problems you can run into in a London office.

A meeting room might normally contain nobody. Then all of a sudden, 10–20 people enter carrying laptops and phones. Several of these people may start video calls, screen sharing or cloud applications.

Within moments, the wireless demand has changed dramatically.

An AP in the corridor outside may technically provide coverage, but not necessarily sufficient capacity or performance.

Modern office design therefore needs to consider where people congregate, how many of them there are and what devices they could be using and for what.

Why adding more access points isn’t automatically the answer

It’s commonly thought that the solution for poor Wi-Fi must just be to buy another Access Point. And of course, more AP’s can be helpful – When they are properly designed.

But indiscriminately just adding more AP’s can actually introduce additional contention and interference, creating further problems.

AP transmit power, channels, channel width and positioning all matter.

Access Points need to form part of a coordinated wireless design. The aim isn’t simply to produce the strongest possible signal everywhere.

Office Construction and Layout

Walk around London and you’ll see it has a huge variety of building types.

From modern glass offices to converted Victorian buildings – All London offices present different Wii-Fi challenges.

When it comes to construction, potential Wi-Fi obstacles include:

Brick
Concrete
Reinforced concrete
Metal
Glass
Lifts
Stairwells
Plant rooms
Dense storage
Partition walls

Any refurbishments can also dramatically alter an RF environment. An Access Point installed before an office fit-out may no longer be positioned appropriately afterwards.

This is just one of the reasons Wi-Fi shouldn’t simply be designed from a square-metre calculation.

Roaming and the “Wi-Fi is bad when I walk around” complaint

Modern offices frequently have multiple APs, which means that devices need to transition between them. Clients ultimately make many roaming decisions themselves.

Poor network design and configuration can make roaming less effective.

Common symptoms of poor roaming:

The Wi-Fi works, then
The user walks towards another part of the building
The laptop/ phone remains connected but performance deteriorates
User understandably reports “the Wi-Fi keeps dropping”.

Increasing the broadband speed isn’t going to fix the issue.

The 9am problem / Busy-office effect

Wi-Fi can appear excellent while an office is empty. The Wi-Fi Engineer performs a speed test at 7pm and gets fantastic results.

9am and it’s a different story. For a London office with 20-200+ employees, between 9 and 10am the next morning, dozens or even hundreds of devices arrive.

Suddenly the demand for airtime increases dramatically. Video meetings start. Cloud applications synchronise.Phones and laptops connect simultaneously.

Performance problems begin to become apparent.

This is a perfect illustration of why testing needs to consider the real operating environment rather than simply headline download speed.

Why just a normal speed test isn’t enough

Speed tests are useful, but only answer a limited question.

Speed Test results can vary according to:

Location
Device
AP
Network load
Time of day

A professional Wi-Fi assessment should consider much more than merely Mbps. Our expert Wi-Fi engineers here at Geekabit can investigate many potential areas including:

Signal strength
Signal-to-noise
Channel utilisation
Interference
Access Point placement
Channel planning
Client distribution
Roaming behaviour
Wired infrastructure feeding APs
Configuration
Actual user experience.

There is considerably more happening beneath the surface, and focusing just on internet speed is unlikely to fix the problem.

Let’s not forget the wired network

Wi-Fi APs ultimately connect back to the wired network. Poor cabling, incorrect negotiation speeds, unsuitable switches, VLAN/configuration problems or inadequate PoE can also cause symptoms that users perceive as “bad Wi-Fi”.

Specialist troubleshooting therefore needs to look beyond the Access Points themselves.

Our approach at Geekabit is to investigate the network as a system rather than automatically blaming one component.

What can a professional Wi-Fi assessment or Site Survey reveal for a business?

There’s a lot that a Wi-Fi Site Survey can tell us about your business wireless network.

Areas with insufficient coverage.
Areas with excessive overlapping coverage.
Congested channels.
Poor AP placement.
Incorrect configuration.
Capacity hotspots.
Problems caused by building construction.
Wired-network issues affecting wireless performance.
Legacy equipment.
Opportunities to optimise the existing infrastructure without necessarily replacing everything.
Locations where additional or relocated APs would genuinely help.

Using the information provided from the Wi-Fi assessment, Geekabit can then provide evidence-based recommendations rather than trial-and-error equipment changes.

Wireless network replacement isn’t always necessary!

We’re not hardware sales people – We just want your network to function at its full potential. Wi-Fi recommendations following a Wi-Fi Site Survey aren’t necessarily going to say ‘replace everything.’ There are times where an existing Wi-Fi system is actually perfectly capable – It’s just the configuration or deployment that is poor.

A specialist assessment may recommend:

Configuration changes
Repositioning equipment;
Replacing particular components
Adding APs only where needed
Upgrading only part of the network.

Recommendations of this nature should be based on evidence, following a Wi-Fi Assessment or Wi-Fi Site Survey.

Geekabit work alongside your existing IT department or company

We know that many London businesses already have an MSP or outsourced IT provider. Any problems with your network don’t automatically mean that your IT Manager / provider is incompetent.

Diagnosing and resolving a complex wireless problem often requires expert knowledge, whereas general IT support covers an enormous range of technologies. A bit like how a GP knows a little about a lot of illnesses, and then refers you to a specialist for more niche diagnosis and treatments. Wi-Fi engineering is a specialist discipline.

Here at Geekabit we can work alongside:

MSPs
internal IT departments
Cabling companies
Office refurb contractors.

Geekabit can investigate the wireless problem, provide evidence based recommendations and work with the incumbent IT provider on remediation.

When should a London business consider calling a Wi-Fi specialist?

If you’ve been struggling with Wi-Fi issues for a while, it may be time to call in a Wi-Fi expert. If your London business is experiencing any of the following issues, please do get in touch with our friendly team.

Internet connection tests well but users still complain
Problems vary significantly depending on location
Wi-Fi gets worse when the office is busy
Meeting rooms regularly experience problems
Video calls are unreliable
Users disconnect when moving around the office
Additional APs haven’t solved the problem
Different engineers/providers have tried fixes without identifying the root cause
Business is moving office or refurbishing an existing one
Organisation is planning a significant Wi-Fi upgrade
There is pressure to replace the entire network without clear evidence of what’s actually wrong

Call in the Wi-Fi experts at Geekabit

Geekabit specialises in Wi-Fi and wireless networking rather than providing generic outsourced IT support. Our Wi-Fi expert engineers are on hand to provide on-site specialist assistance at your London office.

We approach Wi-Fi problems through measurement, diagnosis and evidence.

Our team has experience with business, commercial and complex environments and has the ability to investigate and support both wireless and wired infrastructure.

We are more than happy to work directly for your London business or alongside an existing IT provider.

Before you spend money replacing equipment or buying an even faster internet connection, STOP. It’s worth finding out what the wireless network is actually doing first. As a Wi-Fi Specialist covering London, Geekabit can help your business diagnose the problem and help deploy the solution.

Frequently Asked Questions

Why is my office Wi-Fi slow even though we have fast fibre?

Fast fibre only determines how much internet bandwidth reaches your office. Wi-Fi is the wireless network that distributes that connection to laptops, phones and other devices. Poor access point placement, interference, congestion, insufficient capacity or network configuration issues can therefore cause slow Wi-Fi even when a wired speed test shows a very fast internet connection.

Will upgrading to faster broadband improve our office Wi-Fi?

Not necessarily. If your existing internet connection is already fast enough for your business, upgrading it will not fix problems caused by the Wi-Fi network itself. Before increasing broadband capacity, it is worth establishing whether the bottleneck is the internet connection, the wired network or the wireless network.

Why does our office Wi-Fi get worse when more people arrive?

Wi-Fi uses shared radio airtime. As more laptops, phones and other devices connect and transmit data, they compete for that available airtime. An office Wi-Fi network therefore needs sufficient capacity for the number of devices and the applications being used, rather than simply providing a strong signal throughout the building.

Why is the Wi-Fi particularly bad in our meeting rooms?

Meeting rooms can create sudden areas of high wireless demand. A room that is normally empty might suddenly contain 10 or 20 people, each carrying a laptop and smartphone, while several users are making video calls or accessing cloud services. Good Wi-Fi design considers where users congregate as well as basic coverage.

Can adding more Wi-Fi access points make performance worse?

Yes. Adding access points without considering channels, transmit power, positioning and the existing RF environment can create additional contention and interference. More access points can provide greater capacity and coverage when properly designed, but simply installing additional units is not always the solution.

Why does Wi-Fi work well in one part of our office but badly in another?

Wi-Fi signals are affected by distance, building materials, interference and the position of access points. Brick, concrete, metal, glass, lifts and other structural features can all affect radio signals. A professional Wi-Fi assessment can identify how the wireless network actually performs across the office rather than relying solely on theoretical coverage.

Why does my laptop have full Wi-Fi signal but still feel slow?

A strong Wi-Fi signal does not guarantee good performance. Your device may have a strong connection to an access point that is busy, operating on a congested channel or affected by interference. Wi-Fi performance depends on signal quality, available airtime, network capacity and the underlying network as well as the number of signal bars displayed on a device.

Why does Wi-Fi drop when I walk around the office?

In an office with multiple access points, laptops and smartphones need to roam between them as users move around the building. Devices make many of their own roaming decisions, but access point placement and network configuration can influence how effectively this happens. Poor roaming can result in a device remaining connected to a distant access point even when a better one is available nearby.

What is a professional Wi-Fi site survey?

A professional Wi-Fi site survey assesses how a wireless network performs within a real building or planned environment. Depending on the type of survey, it can examine factors including signal strength, coverage, interference, channel utilisation, access point placement and capacity. The findings can then be used to diagnose problems or design improvements based on measured evidence.

Is a Wi-Fi site survey just a series of speed tests?

No. Speed tests can be useful, but they only show the performance experienced by one device at a particular location and moment in time. Professional Wi-Fi troubleshooting considers the wider radio environment, access point deployment, interference, capacity, configuration and the wired infrastructure supporting the wireless network.

Can network cabling or switches cause Wi-Fi problems?

Yes. Wireless access points ultimately rely on the wired network for connectivity and power. Cabling faults, incorrect Ethernet negotiation speeds, switch configuration problems or power issues can all affect an access point’s performance. Users may experience the result as poor Wi-Fi even though the underlying fault is elsewhere in the network.

Do we need to replace all our Wi-Fi equipment if performance is poor?

Not necessarily. Existing equipment may be perfectly capable but poorly positioned, configured or integrated into the wider network. A specialist assessment should identify the cause of the problem before recommending replacement equipment. In some cases, configuration changes or repositioning existing access points may significantly improve performance.

What is the difference between Wi-Fi coverage and Wi-Fi capacity?

Coverage describes whether a usable wireless signal reaches a particular area. Capacity describes whether the network can adequately support the number of devices and amount of wireless traffic in that area. A modern office can have excellent Wi-Fi coverage but inadequate capacity when large numbers of people are using the network simultaneously.

Why are London offices particularly challenging for Wi-Fi?

London offices are often located in dense commercial environments containing many neighbouring wireless networks. Multi-tenant buildings, neighbouring businesses, complex building materials and high numbers of connected devices can create challenging radio environments. Effective office Wi-Fi therefore needs to account for the surrounding RF environment as well as the size and layout of the premises.

Can Geekabit investigate our Wi-Fi without replacing our existing IT company?

Yes. Geekabit can work directly with businesses, internal IT teams and existing managed IT providers to investigate specialist Wi-Fi and networking problems. The objective is to identify the underlying cause, provide evidence and recommend appropriate improvements rather than requiring a business to replace its existing IT support provider.

When should we call a Wi-Fi specialist?

Consider specialist investigation when Wi-Fi problems persist despite having a reliable internet connection, when performance changes significantly around the building or during busy periods, or when previous attempts to fix the problem have been unsuccessful. A specialist assessment can also be valuable before an office move, refurbishment or significant wireless network upgrade.

How can we tell whether the problem is our broadband or our Wi-Fi?

Comparing wired and wireless performance is a useful starting point. If devices connected directly to the network perform well while wireless devices experience poor or inconsistent performance, the problem may be within the Wi-Fi network rather than the internet connection. A proper assessment can investigate the internet connection, wired infrastructure and wireless environment to locate the actual bottleneck.

Should Wi-Fi be planned before moving into a new London office?

Yes. Planning Wi-Fi before an office fit-out allows access point locations, network cabling and capacity requirements to be considered alongside the physical layout of the space. This can avoid access points being installed wherever cabling happens to be convenient and reduce the need for disruptive changes after staff have moved in.

Wi-Fi Wi-Fi 7 Wi-Fi Advice Wi-Fi Design Wi-Fi Help Wi-Fi Issues Wi-Fi Problems Wireless Network

Why Is My Office Wi-Fi Slow at 9am? Common Causes & Solutions

Does your SME office Wi-Fi grind to a halt every morning? Discover the most common causes of slow business Wi-Fi at peak times and how to fix them.

If you’re an IT Manager who faces a team of colleagues all asking “Has the Wi-Fi gone slow again?” Every Single Morning, then you’re in the right place.

Your internet connection might actually not be the problem. When we get called out to clients, the internet connection is often not the issue. It’s more likely to be the fact that your SME business network wasn’t designed for everyone using it simultaneously.

So what can your internal IT Team or Facilities Manager do about it? Let’s find out.

‘I think the Wi-Fi is down!’ – A familiar scenario in your office?

Picture this. You’re a SME business owner. You get in the office at 7.30am and everything seems fine. The morning creeps on, and anything from 20 to 500 employees start making their way into the office. By 9.15am the problems start –

Teams calls are starting to freeze.
Web pages are taking ages to load.

Staff members are starting to complain that the Wi-Fi is down. Already? Some bright spark reboots the router for the nth day in a row. Things seem to improve, but it’s only temporary.

And the cycle repeats. Every day.

No wonder the Office Manager is tearing their hair out and the Operations Director is more stressed than necessary.

If this scenario sounds all too familiar, then your Wi-Fi is probably suffering from capacity problems rather than broadband issues.

Your Internet Connection Probably Isn’t the Bottleneck

Businesses and Office Managers often blame poor Wi-Fi on:

ISP
Fibre connection
Router

When in reality, the broadband may actually only be using 40–50% of its available bandwidth. With client call-outs, we often see that the congestion is inside the office Wi-Fi.

Internet Speed and Wireless Capacity are two different things. Internet speed and wireless capacity (bandwidth) are different parts of your business network. Internet speed is how fast data travels from the outside world to your home, while wireless capacity is how much total data your Wi-Fi network can handle at once.

Everyone Starts Working at the Same Time

Even with flexible working, everyone coming into the office tends to come in at the same time and start their working day. At 9am, mots of your team arrives and starts work. The typical employee will have multiple devices on them all trying to connect to the office network:

Laptop
Smartphone
Smartwatch
Tablet
Wireless headset

Depending on the size of your SME, that’s anywhere from 10 to 500 people arriving for work – And with 1 employee representing 4 0r 5 connected devices, that’s a lot of Wi-Fi clients accessing your network (we’ll let you do the maths).

Teams and Zoom Change Everything

So let’s say we’ve got 60 employees in the office, each with 4 connected devices, and the majority of them are all hopping on a video call. This generates:

Continuous traffic
Low latency requirements
High airtime usage

Why is video traffic different from web browsing?

When your staff members are trying to use video conferencing (whether that’s Microsoft Teams, Zoom or Google Meet), they’re needing a lot more from your network than if they were just browsing the web or answering emails.

Video traffic is different from web browsing because it uses much more data volume, stays active for longer periods, and sends data in sudden bursts to fill a buffer, whereas web browsing sends short, intermittent requests for small text and image files.

Too Many Devices Can Share One Access Point

You have Access Points throughout your office. And this is where many businesses struggle. Because each Access Point has its own practical capacity. Think of it like a motorway – Everything works well when there’s not too much traffic and everything flows, but as soon as there are too many cars getting on or one really slow driver, everything starts to slow down and cause bottlenecks.

Access Points work on the same premise. If too many devices are connecting to the same Access Point, then performance can collapse rapidly, affecting Airtime, Contention and Retransmissions.

Airtime – The total duration your wireless gadgets spend sending and receiving data over the router’s radio waves. In the analogy we used above, think of it as a shared motorway lane where only one device can “speak” or drive at a time. Because the total amount of time available is limited, how it gets used dictates your network’s speed. All devices on the same channel must take turns using the airtime.
Contention – When multiple devices compete to use the same wireless radio channel at the same time. Key parts of this process include listen before talk (a device checks the airtime first, and waits if another device is sending data), collisions (when 2 devices send data at the same time, the signals crash), and back-off timers (After a collision or a busy channel, each device waits for a random extra period before trying again to avoid a repeat crash).
Retransmissions – The resending of data packets that fail to reach their destination or get damaged during wireless air travel.

More Wi-Fi Bars Don’t Mean Better Wi-Fi

This is one of the biggest misconceptions when it comes to Wi-Fi and understanding your business network.

Strong signal ≠ good performance.

Your signal bars might be full, but that doesn’t automatically mean that the Wi-Fi your device is receiving is as strong.

Signal strength is really only measuring how loudly the Access Point can be heard. What it doesn’t measure or show you is:

Congestion – Lots of devices all competing for bandwidth
Interference – Building infrastructure (like walls and ceilings) blocking the signal
Packet loss – When tiny packets of information get sent from your device but don’t reach their destination
Latency – How long it takes data to travel from your device to the router and back again

Wi-Fi airtime is the total amount of time wireless devices spend transmitting data over your network’s radio frequency. Because Wi-Fi is a shared medium where only one device can transmit at a time on a channel, the devices in your office must take turns. Slower devices take longer to transmit the same amount of data, consuming excessive airtime, so one older device can slow down a whole network.

For all these reasons, a busy office network can have excellent signal, but poor performance.

Why Adding Another Access Point Can Make Things Worse

It’s time to bust some myths. We can see why IT or Office Managers might jump to the conclusion that adding another Access Point will fix the problem. But unfortunately this isn’t necessarily the case, and here’s why.

Your business buys another AP, but you haven’t planned for it. This can cause additional problems like:

Channel conflicts
Co-channel interference
Poor roaming

This is where professional design is vital. Expert Wi-Fi engineers like the ones here at Geekabit can plan your network Access Points so that there are no channel conflicts, no co-channel interference and roaming performance is optimal. And that’s if you even need another AP!

Roaming Problems

People are not sedentary. You jump on a call on your smartphone, whilst walking with your laptop to the meeting room. You nip out of the meeting to grab a coffee from the kitchen. You’re hot-desking and have to move mid-way through the morning. Unfortunately, devices don’t always switch neatly to the nearest available AP. This can results in:

Frozen Teams calls
Dropouts
Delays

A professional Wi-Fi expert can ensure optimum roaming between wireless access points for your office through proper coverage overlap, balanced power levels, and protocol configurations. Key steps include setting a 15% to 20% signal overlap, adjusting transmit power to prevent sticky clients, and enabling fast roaming standards.

Poor Access Point Placement

Are your Access Points located in the best places for optimum performance?

Access Points should not be placed in the following areas:

Hidden above metal ceilings
Inside cupboards
Plant rooms
Behind steel beams
Mounted where convenient rather than where coverage is needed.

These locations are not conducive to decent network signal and coverage.

Older Wi-Fi Equipment Struggles

Is the hardware in your office up to date? Do your colleagues’ devices operate on the same Wi-Fi standard as your hardware?

If you are using hardware (e.g. routers, access points) that operate on an older Wi-Fi standard, then you’re not utilising the tech available to you.

Conversely, if your colleagues’ devices are older and not using a newer Wi-Fi standard when your hardware is, then their device(s) could be slowing down your whole network.

You want to be using the newest available features possible, which is currently likely to be Wi-Fi 7. All hardware and user devices should, where possible, be using the same Wi-Fi standard to ensure efficiency and capacity.

How a Professional Wi-Fi Survey Identifies the Real Problem

Up until now, your Office Manager or Facilities Manager might have been guessing. Your internal IT Team has probably done their best to fix what they think the problem is. But here at Geekabit, we don’t guess. We measure.

We look at all the factors that could be affecting your network performance, including:

Coverage
Capacity
Interference
Channel usage
Client density
Roaming
Heatmaps

Our Wi-Fi engineers don’t just fix symptoms – They identify the root cause and find the solution.

You can read more about our Wi-Fi Site Surveys here.

The Good News

In Wi-Fi excerpt hands, most issues can be resolved without replacing everything.

Sometimes solutions include:

Better AP placement
Channel optimisation
Transmit power adjustments
Additional correctly positioned APs
Modern Wi-Fi standards
Better switching
Network redesign

And in even better news – Geekabit can help with all of these things!

Conclusion

If your Wi-Fi only struggles when everyone is in the office, that’s actually really useful information. It points towards a capacity or design issue rather than an internet problem.

With the right analysis and optimisation, businesses can transform user experience without unnecessary hardware upgrades.

Get in touch today to arrange a professional Wi-Fi assessment.

Frequently Asked Questions

Why does my office Wi-Fi slow down at the same time every day?

This is usually a sign of a capacity issue rather than a broadband fault. As staff arrive and connect laptops, phones, tablets and other devices, the wireless network becomes much busier. If the Wi-Fi wasn’t designed to handle that level of demand, performance can deteriorate rapidly during peak periods.

Why is my internet speed test still fast if the Wi-Fi feels slow?

A broadband speed test measures the connection between your office and your internet provider. It doesn’t measure how efficiently your Wi-Fi is delivering that connection to dozens or hundreds of devices. Your internet connection may be healthy while your wireless network is struggling with congestion or interference.

How many devices can one Wi-Fi access point support?

There’s no fixed number, as it depends on the type of applications being used, the Wi-Fi standard, and the environment. Modern business-grade access points can support many connected devices, but real-world performance depends on how much airtime each device consumes. Activities like video conferencing place far greater demands on the network than simply checking emails.

Will adding another Wi-Fi access point solve the problem?

Not necessarily. If additional access points are installed without careful planning, they can create more interference and actually reduce performance. A professional wireless survey helps determine whether more access points are needed and, just as importantly, where they should be positioned and how they should be configured.

Can Microsoft Teams and Zoom affect Wi-Fi performance?

Yes. Video conferencing applications generate continuous, real-time traffic that is more demanding than typical web browsing or email. When many employees join video calls simultaneously, the wireless network must handle significantly more traffic while maintaining low latency and minimal packet loss.

What is a Wi-Fi site survey?

A Wi-Fi site survey is a detailed assessment of your wireless network. Using specialist tools, engineers measure signal strength, coverage, interference, channel usage, roaming behaviour and capacity. The results help identify the root causes of poor performance and provide clear recommendations for improvement.

Can you fix office Wi-Fi without replacing everything?

In many cases, yes. Performance issues are often caused by poor design, incorrect configuration or unsuitable access point placement rather than faulty hardware. Optimising the existing network can frequently deliver substantial improvements without the cost of a complete replacement.

How can Geekabit help?

Geekabit specialises in business Wi-Fi design, troubleshooting and optimisation. We carry out professional Wi-Fi surveys, diagnose performance issues, and recommend practical, evidence-based solutions that improve reliability, coverage and capacity for businesses of all sizes.

Wi-Fi Wi-Fi Advice Wi-Fi Help Wi-Fi Issues Wi-Fi Problems Wi-Fi Site Survey Wireless Network

What Does a Professional Wi-Fi Site Survey Actually Include?

What did you drop into Google to get here? ‘My Teams calls keep dropping!’ – ‘Why are there dead spots around the office?’ – ‘Why are my warehouse scanners so slow?’

Or maybe you’re an IT Manager and you’ve arrived here in desperation because you’ve got colleagues, staff members and guests constantly moaning at you about the poor Wi-Fi.

It’s common for businesses to only think about a Wi-Fi survey after they’re experiencing problems. Wi-Fi issues you might be facing in your office could sound like:

Teams and Zoom calls dropping
Dead spots around the office
Slow warehouse handheld scanners
Guests complaining about Wi-Fi

However, you could also get ahead and pre-empt any potential problems by getting a Wi-Fi Site Survey before your business does any of these:

New office moves
Warehouse expansion
Increasing staff numbers

However you found us, if you’re looking for an easy-to-understand guide, telling you exactly what a professional Wi-Fi Site Survey involves then you’re in the right place. This comprehensive guide will explain what a Wi-Fi Site Survey is, who needs one and how it’s carried out – Without complex technology jargon.

You might also be interested to know why investing in a Wi-Fi Site Survey can save your business significant time and money. Most people have no idea what actually happens during a professional Wi-Fi survey. We don’t just wander around your office with a laptop you know! A Wi-Fi Site Survey is a structured engineering exercise. So let’s talk about it – Starting from the preparation through to the final report.

What is a Professional Wi-Fi Site Survey?

A Wi-Fi Site Survey is far more than checking signal strength. The purpose is to understand how wireless devices will actually perform within a specific environment.

Every office (and building in general) will behave differently when it comes to Wi-Fi performance, due to construction materials, layout and occupancy. The objective is to understand various factors for your specific premises and requirements, including:

Reliable coverage – Mapping real world radio frequency propagation to ensure reliable coverage throughout
Capacity planning – Ensuring your network can handle the concurrent load of users, devices, and bandwidth-heavy applications
Roaming performance – Evaluating and mapping out exactly how client devices transition between Access Points (APs) without dropping the connection
Voice and video quality – Measuring and validating network metrics required for real-time, delay-sensitive applications and preventing choppy audio, frozen video and dropped calls
Device density – Defining how many concurrent active users are connected in specific areas, and how many devices specific APs are supporting
Future scalability – Establishing a baseline that accommodates increased device density and seamless hardware upgrades (so your network grows with your business)

Why Do Businesses Need a Wi-Fi Site Survey?

There are lots of scenarios where a Wi-Fi Site Survey would be a useful investment for a business. The standard solution to poor Wi-Fi in the workplace seems to be ‘throw another AP at it.’ Whilst this is well-intended (we hope), it can actually do more harm than good to a business network. Which is why it’s always a good idea to carry out a Wi-Fi Site Survey to actually see how your network is functioning in real time and where improvements can be made.

Wi-Fi Site Survey for the Office Refurbishment

If you’re about to refurbish the office, then it’s a great time for a Wi-Fi Site Survey. It’s best to be proactive rather than reactive when it comes to Wi-Fi problems. It’s often overlooked, but new walls and furniture can dramatically change wireless coverage so either arrange a software model-led Site Survey before the refurb goes ahead, or an on site Survey as soon as the walls are up and the furniture is in. This way, you can nip any coverage problems in the bud before employees have the chance to complain!

Wi-Fi Site Surveys for Warehousing

Racking, stock levels and moving forklifts all affect radio signals.A Wi-Fi Site Survey in warehousing can prevent connectivity issues by mapping out how radio frequencies interact with metal racking, high ceilings, and moving inventory. It determines the optimal number and placement of Access Points to eliminate dead zones and prevent dropped connections for handheld scanners, autonomous robots, and Warehouse Management Systems (WMS).

Wi-Fi Site Surveys for Schools

A Wi-Fi site survey can detect interference and plan optimal Access Point placements across a school, college or university campus. This ensures that construction elements like thick walls are accounted for coverage wise, as well as outdoor learning areas in the grounds. A big issue for schools is device density and being able to handle a high load of devices at any one time. Speed is also a vital requirement to keep buffering low and learning high. A Wi-Fi Site Survey can show exactly what’s needed and where, across the whole campus.

Wi-Fi Site Surveys for Hotels

A Wi-Fi Site Survey helps hotels eliminate dead zones, prevent bandwidth bottlenecks, and optimise hardware placement. Improve guest satisfaction, protect online reviews, and reliably support internal operations by mapping radio frequency across room layout and high density areas.

Wi-Fi Site Surveys for Healthcare

A Wi-Fi Site Survey is critical in healthcare because it eliminates signal “guesswork” in complex physical environments. By identifying coverage gaps and interference, it ensures uninterrupted connectivity for life-critical medical devices, seamless roaming for mobile staff, and reliable telehealth access for patients.

Wi-Fi Site Surveys for Manufacturing

A Wi-Fi Site Survey ensures reliable connectivity in harsh industrial environments. It maps signal-blocking obstacles (like heavy machinery and metal structures), mitigates radio frequency (RF) interference, and supports seamless roaming for AGVs (Automated Guided Vehicles), IoT devices, and barcode scanners.

What We Need to Know Before We Even Visit Your Site for a Wi-Fi Survey

Before we set foot on site at your business for your Wi-Fi Site Survey, there are a few things we like to know about. We’ll ask your IT Manager or Infrastructure Manager to send us some information so we can start building a picture of your business and requirements – It’s as important for us to know what your business needs Wi-Fi for as the building itself.

We’ll ask you for some information on:

Floor plans – So we can get a feel for the space
Existing Wi-Fi equipment – What do you already have and where?
Internet connection – What type (fibre, broadband etc)
Existing switches
Building construction
User numbers – How many members of staff? Do you use contractors? Do you have many visitors?
Types of devices – What devices do your users use?
Business-critical applications – What would be catastrophic to lose if your Wi-Fi went down?
Areas requiring guaranteed coverage – Similar to the above
Future expansion plans – Will your business be growing? Physically in terms of structure and/ or staffing

What to Expect on Wi-Fi Survey Day

Let’s take it step by step for what to expect on the day we visit to conduct your Wi-Fi Site Survey.

Initial Walkthrough

We’ll start with an initial walkthrough of your office / business premises so our Wi-Fi engineer can understand the layout and identify any unusual challenges.

Existing Network Review

Our Wi-Fi engineer will check current Access Point locations, switch cabinets and cabling.

Measuring Signal

Next we’ll begin measuring signal, collecting thousands of measurements throughout the building.

Measuring Interference

Next we’ll be looking at Interference and identifying neighbouring Wi-Fi networks and non-Wi-Fi interference to see what could cause problems to the network.

Capacity Testing

This will look at and assess whether the network can cope with the expected device numbers.

Roaming Tests

Our Wi-Fi engineer will take a walk while making calls to verify seamless handover between Access Points.

Throughput Testing

Our Wi-Fi engineer will measure real-world performance rather than just the headline internet speed. Is the speed of your internet transmitting to the rest of your network? If not, why not?

A Wi-Fi Site Survey can often take a few hours to complete, depending on the size of the building(s) and layout of the premises.

What is the Technology Behind a Wi-Fi Site Survey?

A Wi-Fi Site Survey from Geekabit utilises professional survey tools, calibrated wireless adapters and spectrum analysis equipment.

If you’re thinking ‘surely there’s an app for this?’ then you would be right – But consumer phone apps cannot produce anywhere near the same quality of data as a professional Wi-Fi Site Survey. Our surveys are vendor-neutral, meaning you can use them with your internal IT team, a third-party installer, or ourselves here at Geekabit.

Our tools use concepts like the below to build a complete picture of your network:

RSSI – Received Signal Strength Indicator. It is a measurement of the power level of a wireless signal (such as Wi-Fi or Bluetooth) that a device’s antenna is receiving.
SNR – Signal to Noise Ratio. A metric used to compare the level of a desired signal to the level of background noise. Expressed in decibels (dB), a higher SNR means a clearer, higher-quality signal.
Channel utilisation – The percentage of total capacity or time that a communication channel (such as a Wi-Fi frequency) is actively busy transmitting data, management signals, or dealing with interference.
Interference – Identifying the occurrence of when neighboring networks, devices, or non-Wi-Fi gadgets broadcast on the same or overlapping frequencies.
Airtime – Looks at the amount of time a specific wireless channel is occupied by devices actively transmitting or receiving data. Because Wi-Fi operates on shared radio frequencies, only one device can transmit at a time, making total airtime a strictly limited, finite resource.
Packet loss – Identifying the occurrence of when data traveling across your wireless network fails to reach its destination. Instead of arriving seamlessly, tiny chunks of data (packets) go missing causing issues like dropped calls.

Active vs Passive vs Predictive Surveys

There are different types of Wi-Fi Site Survey. Let’s take a look at each one.

Passive Wi-Fi Site Survey

Essentially, this is just listening to the existing Wi-Fi, creating a birds-eye view.

A passive Wi-Fi site survey is a non-intrusive method where a surveying device quietly listens to the wireless environment without connecting to a network. It is used to map existing coverage, identify dead zones, and detect interference by measuring broadcast signals (such as beacons) from nearby Access Points (APs). The tool quietly gathers raw radio frequency (RF) data to build visual heatmaps using information on RSSI, SNR, background interference and channel utilisation.

Passive surveys are ideal for a general health check of a building’s wireless landscape.

Active Wi-Fi Site Survey

In an Active Wi-Fi Survey, the surveying device connects to a specific WLAN and actively sends test traffic to measure real-world performance, such as round-trip packet loss, upload/download speeds, and roaming behavior between APs.

It’s a physical walk through simulating actual user experience by measuring throughput rates, latency, packet loss and roaming performance.

Active surveys are relied on primarily for post-deployment validation and troubleshooting, used for verifying network upgrades, troubleshooting poor user experience and to test roaming.

Predictive Survey

A predictive Wi-Fi site survey is a software simulation used to design a wireless network before any physical hardware is installed. By uploading digital floor plans into specialized RF (radio frequency) modeling software, engineers map out the optimal number, placement, and configuration of access points (APs) based on wall materials, building scale, and expected user capacity.

Predictive surveys are highly cost-effective and are typically utilized during the early planning stages or before a building is constructed or renovated. They allow network architects to test different AP mounting scenarios virtually to prevent signal blind spots and avoid costly cabling changes post-installation.

For a complete picture, our Wi-Fi engineers at Geekabit often perform both a Passive and Active survey: Passive surveys to find physical coverage limits and interference, followed by Active surveys to test performance and roaming capabilities.

For scenarios where being physically on site isn’t possible, we can use a Predictive Survey to plan a network deployment.

What Will You Receive After Your Wi-Fi Site Survey

Once the Wi-Fi Site Survey has been completed, we can provide your business with a detailed report with clear, practical recommendations to improve your Wi-Fi performance, reliability, and user experience.

This report is based on key deliverables such as:

Executive summary
Coverage heatmaps
Signal strength maps
Capacity maps
Interference analysis
Access point placement recommendations
Channel planning
Power level recommendations
Cabling recommendations
Hardware recommendations
Prioritised improvement plan

A detailed report of this nature takes all the guesswork out of the deployment of a wireless network as well as solving any troubleshooting issues. This means your business can make an informed decision about how to get your network performing at its best.

What Are The Most Common Problems We Discover from a Wi-Fi Site Survey?

There are quite a few things that can show up on a Wi-Fi Site Survey. The most common things we see are:

Access points hidden above suspended ceilings
Too many access points competing
Consumer Wi-Fi equipment in commercial buildings
Poor channel planning
Faulty Ethernet cabling
Network loops
Incorrect transmit power
Devices clinging to distant access points

Metal shelving blocking signals

Any of these issues sound familiar?

How Long Does a Wi-Fi Site Survey Take?

The length of time a Wi-Fi Site Survey takes depends on a few influencing factors, including:

Building size
Number of floors
Required detail
Existing infrastructure
Whether trading continues during the survey

Once we know a bit more about your business, we can give an educated estimate of how long it could take.

Section 10 – Frequently Asked Questions

FAQ: Will a Wi-Fi site survey disrupt our business?
In most cases, no. A professional Wi-Fi site survey is designed to be as non-disruptive as possible. Survey engineers typically walk around your premises collecting wireless measurements while your staff continue working as normal. If active testing is required, such as roaming or throughput tests, these are usually carried out without affecting other users. For businesses that operate around the clock or have sensitive environments, surveys can often be scheduled outside normal working hours.

FAQ: Do staff need to stop working during the survey?
No. Employees can usually continue using the network throughout the survey. In fact, carrying out the survey while the office is occupied can provide a more realistic picture of how the wireless network performs under normal day-to-day conditions. In some cases, your survey engineer may ask for access to specific rooms or equipment, but disruption is generally minimal.

FAQ: Can a Wi-Fi survey be carried out outside business hours?
Yes. Many organisations prefer surveys to be completed during evenings or weekends to minimise disruption. However, it’s worth remembering that an empty building behaves differently from one full of people and connected devices. Depending on your objectives, your survey provider may recommend carrying out some measurements during normal operating hours to capture real-world performance.

FAQ: What is the difference between a predictive and an active Wi-Fi survey?
A predictive survey uses digital floor plans and specialist software to model how Wi-Fi signals are expected to behave before any equipment is installed. An active survey is carried out on-site using a live wireless network, measuring real-world performance such as signal strength, roaming behaviour, throughput and latency. Predictive surveys are ideal for new buildings or refurbishments, while active surveys are best for troubleshooting existing Wi-Fi issues.

FAQ: How long does a professional Wi-Fi site survey take?
The time required depends on the size and complexity of your premises. A small office may take a few hours, while larger offices, warehouses, schools or hospitals may require a full day or more. Additional time is also needed to analyse the data and produce a detailed report with recommendations. The survey itself is only one part of the overall process.

FAQ: How often should a Wi-Fi site survey be repeated?
There is no fixed schedule, but it’s sensible to consider a new survey whenever your environment changes significantly. Examples include office refurbishments, building extensions, increased staff numbers, new warehouse racking, or upgrades to your wireless infrastructure. Many organisations also commission a survey every few years to ensure their network continues to meet changing business requirements.

FAQ: Is a Wi-Fi survey worthwhile before moving into a new office?
Yes. A predictive Wi-Fi survey can help identify the best locations for access points before cabling and equipment are installed. Planning the network early can reduce installation costs, avoid unnecessary hardware purchases and help ensure reliable wireless coverage from day one. It’s often far easier and more cost-effective to design a network correctly than to fix problems after staff have moved in.

FAQ: Can you carry out Wi-Fi surveys in warehouses?
Absolutely. Warehouses present unique wireless challenges due to high shelving, metal racking, changing stock levels and large open spaces. A professional survey takes these factors into account to ensure reliable connectivity for handheld scanners, tablets, voice devices and industrial equipment throughout the building.

FAQ: Do schools benefit from Wi-Fi site surveys?
Yes. Schools place heavy demands on wireless networks, with hundreds or even thousands of devices connecting simultaneously. A survey can help ensure classrooms, halls, libraries and communal spaces all receive reliable coverage, while also assessing whether the network has sufficient capacity for modern teaching methods and online assessments.

FAQ: Will a Wi-Fi site survey tell me if I need new equipment?
Not necessarily. One of the main benefits of a professional survey is that it provides evidence rather than assumptions. Sometimes the existing equipment simply needs repositioning, reconfigured or optimised. In other cases, additional access points or newer hardware may be recommended. The goal is to identify the most effective solution rather than automatically recommending replacement equipment.

FAQ: Can a Wi-Fi site survey improve Microsoft Teams and Zoom calls?
Yes, if poor Wi-Fi is contributing to the problem. Video conferencing applications rely on low latency, stable roaming and minimal packet loss rather than simply high download speeds. A survey can identify issues such as interference, overloaded access points, poor signal quality or incorrect channel planning that may be affecting call quality. Once these issues are addressed, users often experience more reliable voice and video performance.

FAQ: Can I perform a Wi-Fi site survey myself?
Basic smartphone apps can give you a rough indication of signal strength, but they don’t provide the level of detail needed to design or troubleshoot a business-grade wireless network. Professional surveys use calibrated hardware and specialist software to measure signal quality, interference, roaming behaviour, channel utilisation and many other factors. For small home networks, DIY tools may be sufficient, but businesses that depend on reliable Wi-Fi will generally benefit from a professional survey.

FAQ: What will I receive after the survey?
Most professional Wi-Fi surveys include a detailed report explaining the findings and recommended improvements. This typically includes wireless heatmaps, coverage analysis, interference measurements, access point placement recommendations, channel planning guidance and an executive summary written in plain English. The report provides a clear roadmap for improving your wireless network, whether that involves simple configuration changes or a complete redesign.

Are You Ready to Book Your Wi-Fi Site Survey?

A professional Wi-Fi survey is about understanding how people actually use the network, not just measuring signal bars.

Office Wi-Fi Wi-Fi Wi-Fi Advice Wi-Fi Design Wi-Fi Help Wi-Fi Issues Wi-Fi Problems Wi-Fi Site Survey Wireless Network

Why Does My Office Wi-Fi Keep Disconnecting Randomly? (Even Though the Signal Looks Strong)

We’ve all been there at some point. The signal looks strong, but the Wi-Fi keeps disconnecting. It’s an extremely common business complaint.

Many companies immediately jump to blame their ISP – Surely it must be the broadband provider! But this isn’t necessarily the case every time a member of staff reports random disconnections.

Our Wi-Fi engineers often find that the broadband is actually working perfectly – And the problem instead lies with the office wireless network.

Modern businesses and offices now rely on cloud applications, Microsoft Teams, VoIP phones, VPNs and remote desktops. Unfortunately (or perhaps fortunately?), this also means that Wi-Fi issues are exposed much quicker than they would if employees were only using the internet for browsing the web.

Did you know that ‘strong signal’ and ‘good Wi-Fi’ are not the same thing? Well, now you do.

This article is going to explain the most common causes of disconnecting Wi-Fi in the office and how professional Wi-Fi experts can go about diagnosing the problem.

What “Random Disconnects” Actually Look Like

What does a ‘random disconnect’ look like in real world terms in a modern office or business? Your IT Managers might be getting reports of:

Microsoft Teams calls freezing for a few seconds before reconnecting
Zoom meetings dropping unexpectedly
VPN connections disconnecting while working remotely
Cloud software logging users out unexpectedly
Remote Desktop sessions disconnecting
File uploads stopping midway through
Wi-Fi printing intermittently failing
Mobile phones switching to 4G because Wi-Fi briefly stopped responding

Of course, IT Managers might also be getting much more vague complaints that are less specific to a current issue but sound a bit like:

“The internet keeps going funny.”
“Everything just pauses.”
“It’s fine most of the time.”
“Only happens in certain meeting rooms.”
“It works after I turn Wi-Fi off and back on.”

The problem with intermittent Wi-Fi faults like this is that they are often harder to identify as they don’t leave behind much evidence or any obvious problem other than “the Wi-Fi is hanging.”

Why Signal Bars Don’t Tell the Whole Story

Your signal bars might be full, but that doesn’t automatically mean that the Wi-Fi your device is receiving is as strong.

Imagine 5 people in the same room, all shouting. Everyone in the room can hear each other clearly, but actual communication is difficult.

Signal strength is really only measuring how loudly the Access Point can be heard. What it doesn’t measure or show you is:

Congestion – Lots of devices all competing for bandwidth
Interference – Building infrastructure (like walls and ceilings) blocking the signal
Packet loss – When tiny packets of information get sent from your device but don’t reach their destination
Latency – How long it takes data to travel from your device to the router and back again

For all these reasons, a busy office network can have excellent signal, but poor performance.

The Most Common Causes of Disconnecting Wi-Fi in an Office

Poor Wi-Fi Roaming

Devices can often cling to an Access Point for too long, instead of moving to one with a better location. This is known as a “sticky client.” This could look like a colleague walking around the office with their laptop connected to an AP at the opposite end of the building.

Modern enterprise systems help devices to roam efficiently – But they only work if they are correctly designed and deployed.

Poor Wi-Fi roaming can cause:

Delays
Dropped calls
Temporary loss of connectivity

Channel Interference

Channel Interference can happen when nearby offices use overlapping channels, or when there are multiple neighbouring Wi-Fi networks.

Co-channel interference occurs when separate devices or networks use the identical frequency channel simultaneously. Adjacent channel interference happens when devices operate on overlapping or closely neighboring frequencies, causing signal “bleeding”. While co-channel forces devices to share airtime and wait their turn, adjacent channel is usually more disruptive as it corrupts data.

Things like the office microwave can also cause interference with Wi-Fi networks as they run on the same frequency band.

Bluetooth congestion also causes channel interference issues. Bluetooth and Wi-Fi share the crowded 2.4 GHz unlicensed frequency band. When multiple devices attempt to transmit data on overlapping frequencies simultaneously, packet collisions occur. Devices then drop connection or slow down to retransmit lost data. Bluetooth mitigates this via Frequency Hopping, but heavy congestion in small areas causes interruptions.

Channel planning is a really important step when designing Wi-Fi networks, but is often overlooked.

Too Many Devices on One Access Point

Whilst one AP may technically be able to support many devices, performance does depend on the workload. If employees are heavily using video conferencing then this is going to consume significantly more airtime than, for example, email would.

You may also find that employees congregating in a meeting room suddenly creates a spike in demand. Guest devices can also increase contention.

Adding another AP might seem like the simple solution, but in order to work effectively it must be designed correctly.

Incorrect Power Settings

An Access Point (AP) does not need to run at full transmit power because a loud, high-powered signal can cause client communication imbalances, creates overlapping interference, and ruins wireless roaming.

A lower power setting often yields better Wi-Fi performance because:

Two-Way Communication Balance – The receiving device needs to be able to transmit back to the AP, so if the AP is transmitting at full power and reaching a device that’s too far away to return the signal, it can cause dropped packets, high retry rates and lag.
Preventing “Sticky” Clients: Devices like phones tend to latch onto the strongest Wi-Fi signal they can hear. If an AP broadcasts at full power, a client will stay connected to a distant AP even when walking right past a closer one, resulting in terrible performance and inefficient roaming.
Minimizing Interference: Powerful signals bleed through walls. In multi-AP environments, high power leads to overlapping coverage and Co-Channel Interference (CCI), effectively clogging up the available airtime.

So whilst IT Managers might respond to “poor Wi-Fi” by turning up the power on AP’s, that might actually cause more problems. Professional tuning helps to provide a better balance and thus, better Wi-Fi performance for the office.

Consumer Wi-Fi in Business Environments

Many SME’s (and even some bigger companies!) think they can get away with consumer Wi-Fi with ISP-provided routers and domestic mesh systems. But these are designed for homes, not offices.

Just sticking in a plug-in Wi-Fi extender and powerline adapter is not going to work in an office with dozens or even hundreds of users moving around throughout the day.

An office needs business Wi-Fi, designed for a business environment.

Firmware or Controller Issues

9 times out of 10, Wi-Fi problems come down to configuration issues. However, occasionally our Wi-Fi engineers see problems arise from:

Firmware bugs
Failed updates
Incompatible client devices
Controller software problems
Hardware faults

It is very important to keep up with updates, but in a controlled manner where firmware updates are monitored and checked rather than just automatically installing every new release straight away.

How Wi-Fi Professionals Diagnose These Office Internet Problems

How do us Wi-Fi professionals identify the problems in a troublesome office wireless network? We have a lot of tools at our disposal to diagnose Wi-Fi problems and lead network design.

Here are some of the tools we use as Wi-Fi engineers to help fix your wireless network.

Wi-Fi Heatmaps

Used to:

Measure coverage.
Identify dead zones.
Detect excessive overlap.

Spectrum Analysis

Finding non-Wi-Fi interference.
Identifying hidden RF noise.

Client Analysis

Looking at roaming behaviour.
Retry rates.
Disconnect events.

Packet Captures

Understanding authentication failures.
DHCP problems.
DNS delays.
Application behaviour.

Channel Planning

Selecting optimal channels.
Reducing interference.
Balancing utilisation.

Whilst your IT department might tell you to turn it off and on, diagnosing Wi-Fi is rarely about guessing. It relies on precise measurement and knowing what to do with that data in order to design and deploy the most efficient network possible for your business or office.

Why Rebooting Often “Fixes” Things

It’s the age old joke, isn’t it – Just turn it off and on again! Ta-dah! It’s miraculously fixed. But is it, really? Let’s take a look at why rebooting often looks like it’s solved the problem.

When we reboot something, or turn it off and on again, here’s what’s actually happening:

Temporary memory is cleared
Clients are disconnected and then reconnected
Radio utilisation is reset
Congestion is temporarily reduced
Stuck processes are cleared

In the short term, great, it seems to get things back on track. But underneath the surface…

Poor coverage remains
Interference remains
Incorrect design remains
Roaming problems remain

And that’s exactly why the problem usually returns a few days later, if not sooner!

Can You Troubleshoot It Yourself?

Sometimes your IT team will be able to fix it. Sometimes even a well-versed-in-Wi-Fi colleague will manage to get things working better. Things that members of your team can very much keep on top of are:

Occasionally rebooting your networking equipment
Carefully updating firmware
Considering careful placement of hardware (e.g. not putting AP’s in cupboards or above metal ceilings)
Separating guest traffic from the main network
Using a wired connection wherever it’s practical to do so
Not relying solely on signal bars or internet speed tests

If problems remain, then it may be time to dig a little deeper.

Exactly where are issues occurring?
Are particular issues happening at certain times of day?

When things don’t improve with the obvious fixes and troubleshooting ideas, then it may be time to call in the professionals to help you get to the bottom of your office Wi-Fi problem.

When It’s Time for a Professional Wi-Fi Survey

Signs that you should call the Wi-Fi experts and arrange a Wi-Fi Survey are:

Staff that complain every week about the Wi-Fi
Video meetings regularly failing
Phones disconnecting when moving around the office
Warehouse scanners losing connection
Barcode scanners pausing
VoIP calls breaking up
Worsening Wi-Fi as the business has grown
Multiple DIY fixes not helping
You’re moving office
You’re refurbishing existing premises

A Wi-Fi Survey might be viewed as an unnecessary expense, however, the price of a Wi-Fi Survey is significantly less than the hidden productivity losses caused by unreliable Wi-Fi.

Conclusion

Reliable Wi-Fi is rarely about simply buying expensive hardware, but more about intelligent network design.

A strong signal does not guarantee reliable performance, and there are many factors to consider when designing and deploying a wireless network for an office or business.

Employees shouldn’t need to even think about the Wi-Fi – They should be able to simply get on with their jobs with a wireless network that supports their productivity.

Investing in the right Wi-Fi design from the outset can save significant time and frustration in the future.

If your office is experiencing persistent wireless issues, then please do contact our expert Wi-Fi engineers here at Geekabit to arrange an independent assessment of your network.

FAQ Answers

Why does my Wi-Fi disconnect even when I have full signal?

Signal strength only indicates how well your device can hear the access point. It doesn’t reflect interference, congestion, packet loss or roaming issues. It’s entirely possible to have full signal while experiencing unreliable connectivity.

Can too many devices cause Wi-Fi to disconnect?

Yes. Every device shares the available wireless airtime. As more devices compete for access—particularly those using video conferencing or large file transfers—performance can suffer, leading to delays or temporary disconnections.

Why do Microsoft Teams calls keep dropping on Wi-Fi?

Video calls are sensitive to even brief interruptions. Roaming issues, interference, congestion or packet loss that go unnoticed during web browsing can quickly disrupt Teams calls, causing freezing, poor audio or dropped meetings.

Should I buy more wireless access points?

Not necessarily. More access points can improve coverage, but if they’re positioned or configured incorrectly they can actually increase interference and make performance worse. Network design is just as important as the number of access points.

Can my broadband be fine but my Wi-Fi still be the problem?

Absolutely. Many businesses have fast broadband connections but experience poor wireless performance because of interference, poor coverage, outdated equipment or incorrect configuration inside the office.

Does rebooting my Wi-Fi actually solve the issue?

Rebooting can temporarily improve performance by reconnecting devices and clearing temporary faults, but it rarely addresses the underlying cause. If problems return regularly, further investigation is usually needed.

How do professionals diagnose Wi-Fi problems?

Professional engineers use specialist tools to create coverage heatmaps, analyse radio frequency interference, review client behaviour, capture network traffic and assess channel usage. This allows them to identify the root cause rather than relying on guesswork.

What’s the difference between interference and weak signal?

Weak signal means your device struggles to hear the access point. Interference occurs when other devices or nearby networks compete for the same radio frequencies, disrupting communication even if the signal itself appears strong.

How long does a business Wi-Fi survey take?

The duration depends on the size and complexity of the premises. Small offices may take a couple of hours, while larger buildings or warehouses can require a full day or more. The survey includes detailed measurements and recommendations.

Can older laptops or phones cause Wi-Fi problems?

Older devices can struggle with modern wireless standards or remain connected to distant access points for longer than they should. While they’re not always the root cause, a mixture of old and new devices can highlight weaknesses in a poorly designed network.
